How many primes become 'invisible' -- absorbed by the ring's structure -- at each level of growth? Fibonacci. Exactly. For 15 levels. Then the chain builds its own desert and closes. Lambda = 420 is forced by the mod-49 channel: 7^2=49 contributes 42 to the lcm, pushing the Carmichael period from 60 (Z/2,310) to 420 (Z/12,612,600). Crystallized across five growth factors 2*2*3*5*7 over 15 levels.
Start from lambda=1. Multiply by one growth factor per level. Count invisible primes f(lambda) = number of primes q where (q-1) divides lambda. Result: f = Fibonacci.
| Level | lambda | Growth | f(lambda) = F(k+2) |
|---|---|---|---|
| 0 | 1 | - | 1 = F(2) |
| 1 | 2 | 2 | 2 = F(3) |
| 2 | 4 | 2 | 3 = F(4) |
| 3 | 12 | 3 | 5 = F(5) |
| 4 | 60 | 5 | 8 = F(6) |
| 5 | 420 | 7 | 13 = F(7) |
| 6 | 5460 | 13 | 21 = F(8) |
| 7 | 60060 | 11 | 34 = F(9) |
| 8 | 240240 | 4 | 55 = F(10) |
| 9 | 4564560 | 19 = f(5) | 89 = F(11) |
| 10 | 173453280 | 2*19 = 38 | 144 = F(12) |
| 11 | 16824968160 | 97 | 233 = F(13) |
| 12 | ~1.19*10^13 | 709 | 377 = F(14) |
| 13 | ~1.73*10^16 | 1447 | 610 = F(15) |
| 14 | ~3.35*10^18 | 2*97 = 194 | 987 = F(16) |
All 15 levels match Fibonacci exactly. f(lambda_k) = F(k+2) for k = 0 to 14. Verified computationally at every level.
Lambda = 420 divides into channel sub-cycles. Each CRT channel runs its own clock within the period:
| Channel (mod q) | Cycles = 420/phi(q) | Name | Clock Ratio |
|---|---|---|---|
| mod 8 | 105 | 105 | 3/2 (fifth) |
| mod 9 | 70 | 2*5*7 | 5/3 (Kolmogorov) |
| mod 11 | 42 | 42 | 1/2 (octave) |
| mod 25 | 21 | 3*7 | 3/7 |
| mod 49 | 10 | 2*5 | slowest clock |
| mod 13 | 35 | 5*7 | 5*7 |
Lambda = 420 contains six nested clocks. Each prime channel completes its sub-cycle at a different rate. Enter any number to see which clocks tick at that position. Try 420 (all tick), 42 (mod-49 clock cycle), 105 (mod-8 clock cycle), 12 (= lambda(Z/210) = 4*3).
Enter a lambda position:
Transform cost = 11 THEOREM: the signed sum of chain terms minus signed growth terms = 11.
| Level | Valid g | Prime % | Phase |
|---|---|---|---|
| 1 | 965 | 11.9% | Open -- many composites |
| 6 | 65 | declining | Pre-transition |
| 7 | 10 | 80% | 11-TRANSITION |
| 8-9 | 13-19 | 92-95% | Crystallizing |
| 10-13 | 11-15 | 100% | PURE CRYSTAL |
| 14 | 2 | 50% | Break: 2*97 composite |
| 15 | 0 | - | CHAIN TERMINATES |
Crystallization holds for levels 10 to 10+3 = 13. Level 14 = 7+7: composite returns via 2*97. 7 controls the drop period. 11 initiates crystallization (level 7), 7 terminates it (level 14 = 2*7).
An element n of Z/NZ is nilpotent if n^k = 0 for some k -- it eventually vanishes under repeated multiplication. How many nilpotents does the ring have? Exactly lambda = 420. At every prime-power ring level.
The chain terminates at level 3*5 = 15 because it builds its own grave:
Density decay across levels: chain phase has d = 1.000 (all growths are chain primes). Mixed phase: rapid decline. Terminal phase: d(k) = 1.307*e^(-0.172k). Rate 0.172 is approximately log(phi)/log(11) = 0.201. Each level: 84% survives. The chain terminates when prime density can no longer sustain exact Fibonacci growth.
Extending to all 7 chain primes and ring-level Pisano periods reveals the 105 growth theorem. The extension primes {13, 17} have Pisano periods 4*7 = 28 and 4*9 = 36 -- chain-smooth, with ranks of apparition alpha(13) = 7 and alpha(17) = 9.
| Prime p | pi(p) | alpha(p) | pi/alpha |
|---|---|---|---|
| 2 | 3 | 3 | 1 |
| 3 | 8 | 4 | 2 |
| 5 | 20 | 5 | 4 |
| 7 | 16 | 8 | 2 |
| 11 | 10 | 10 | 1 |
| 13 | 28 | 7 | 4 |
| 17 | 36 | 9 | 4 |
The chain primes emerge from cyclotomic polynomials evaluated at 2:
| n | Phi_n(2) | Identity | Note |
|---|---|---|---|
| 1 | 1 | 1 | Identity. |
| 2 | 3 | 3 | Phi_2(2) = 2+1 = 3. |
| 3 | 7 | 7 | Phi_3(2) = 4+2+1 = 7. |
| 4 | 5 | 5 | Phi_4(2) = 4+1 = 5. |
| 8 | 17 | 17 | ord(2,17) = 8. |
| 10 | 11 | 11 | ord(2,11) = 10. |
| 12 | 13 | 13 | Enters at lambda(Z/210) = 12. |
Smooth Phi_n(2) indices: {1,2,3,4,6,10}. Count = 2*3 = 6. The chain-smooth Mersenne exponents {1,2,3,4,6} = proper divisors of 12 = lambda(Z/210). f(x) = Phi_6(x) - 2: the polynomial p^2-p-1 IS the 6th cyclotomic polynomial shifted by 2.
How many rings share a given lambda? The lattice freedom at each level can be decomposed into three additive tower contributions -- one from each class of boundary prime.
Proved theorems on the Proof Assistant page that directly concern lambda = 420:
| # | Theorem | Key result |
|---|---|---|
| 140 | CRT Nilpotent Count | Nilpotent count = 420 at all prime-power levels. Per-channel {4,3,5,7}. Inner channels {2,5,7} contribute 140. |
| 153 | Free Sum Triangular | free_sum = T(e_E) + g*2^(e_E) + s. Three tower contributions. Column product = 432 = d(TRUE). |
| 156 | Cyclotomic Order | p = Phi_{ord(2,p)}(2). 2^12-1 = 9*5*7*13. Maximal segment = 7. |
| 193 | Fibonacci-Pisano Structure | All 7 pi(p) chain-smooth. Sum = 11^2. Ring-level growth = 105. pi/alpha = 2 uniform. |
| Claim | Standard | Ring Structure |
|---|---|---|
| Carmichael's lambda | Technicality of modular arithmetic | 420 = 4*3*5*7. All 108 rings sharing this lambda do so exactly (7^2 forced). Of those 108: 84 divide Z/12,612,600 (mod-8 range 0..3); 24 extensions reach 2*Z/12,612,600 (mod-8 = 4). mod-49 channel ceiling forces it: 7^2=49 contributes 42 to the lcm, pushing 60 (Z/2,310) to 420 (Z/12,612,600). Crystallized across 5 growth factors. |
| Fibonacci sequence | Rabbit counting, golden ratio curiosity | Counts invisible primes at 15 levels. Growth recursion: new = f(lambda_{k-2}). Golden ratio bound: new/need -> 1/phi. |
| Why 420? | Just an LCM | Product of chain growth factors 2*2*3*5*7. Born at level 5 where f(420) = 13. The chain sees itself. |
| Fibonacci periods | Modular periodicity | Pisano at chain primes gives E8: lcm = 240 = |roots(E8)|. Seventh independent path. |
| Desert termination | Prime gaps get large | Desert pair {1596,1597} at level 3*5=15. 1597 = F(17). The chain closes when Fibonacci reaches the 17th index. |
| Cyclotomic polynomials | Abstract algebra tool | Phi_n(2) = {1,3,7,5,17,11,13}. Cyclotomic ORDER of 2 mod p explains ring-level ordering: p enters when ord | lambda(N). First 7 = maximal segment. |
| Nilpotent elements | Degenerate edge case | Count = 420 = lambda at all prime-power levels. Per-channel {4,3,5,7}. The Carmichael period counts the nilpotents. mod-8 channel doubles it: lambda/210 = 2. |
The chain grew for 3*5 = 15 levels. At level 5, lambda = 420 is reached. The desert pair blocks the 15th step. 2 carries the chain and creates its end.
