Eleven Terms

{-1, 0, 1, 2, 3, 5, 7, 11, 13, 17, 26801776}

Eleven terms. Not chosen -- forced. Each is an operation the ring performs on a number. Three structural anchors (-1, 0, 1), seven primes from two Cunningham chains (2, 3, 5, 7, 11, 13, 17), and the terminal projector 26,801,776 = 2^1680 mod 214,414,200. Together they form a complete computational vocabulary. 3 + 7 + 1 = 11 = the protector prime.

The Eleven Operations

Three operators. Seven primes. One projector. The count is 11 -- itself the 5th axiom prime.

-1
n -> N - n
Additive inverse. CRT(-1) = all channels at their maximum residue.
0
n -> 0
Absorbs. 0*n = 0 for all n. The universal annihilator.
1
n -> n
Identity. 1*n = n.
2
n -> 2n
The only even prime. Generates CRT decomposition into 7 channels.
3
n -> 3n
Minimum for majority vote and triangles. c(1) = 3.
5
n -> 5n
5^2 = 25 = 0 mod 25: self-blind in its own channel. c(2) = 5.
7
n -> 7n
Deepest channel: 49 states in mod-49. Controls the spectral gap. c(3) = 7.
11
n -> 11n
1+2+3+5 = 11. Error detection via mod-11 parity. c(5) = 11.
13
n -> 13n
2^2 + 3^2 = 13. lambda(13) = 12 divides 420. Closes the 6-channel ring.
17
n -> 17n
5*7 = 1 mod 17. phi(17) = 2^4. Opens the 7th channel. Completes the ring.
26,801,776
n -> 26,801,776*n
Terminal projector: 2^1680 mod 214,414,200. CRT = (0,1,1,1,1,1,1). Zeros out the mod-8 channel, preserves all six others. Idempotent: x^2 = x.

Why 13 and 17

13 closes the 6-channel ring. 17 opens the 7th channel. Both are forced:

13: lambda-compatible
lambda(13) = 12 | 420
12 divides 420. Adding 13 preserves the Carmichael period. The 6-channel ring Z/12,612,600 has lambda = 420.
17: lambda-extending
lambda(17) = 16
lcm(420, 16) = 1680. Adding 17 extends the period from 420 to 1680 = 4*420. The 7th channel needs 4x more steps.
13: sum of squares
2^2 + 3^2 = 13
Shadow: (13-1)/2 = 6 = 2*3. Both Cunningham chains terminate before reaching 13.
17: product identity
5*7 = 1 mod 17
The product of two inner primes is the identity in mod-17. phi(17) = 16 = 2^4.
13: CRT encoding
CRT(13) = (5, 4, 13, 13, 2, 0, 13)
13 encodes itself across seven channels and vanishes in its own (13 mod 13 = 0).
17: CRT encoding
CRT(17) = (1, 8, 17, 17, 6, 4, 0)
17 vanishes in its own channel (17 mod 17 = 0). mod-8 = 1: invisible to the even channel.
Primitivity Theorem (PROVED)
ord(13) = 420 = lambda in Z/970,200. 13 achieves maximal multiplicative order. Per-channel orders: (2, 3, 20, 14, 10). Sum = 49 = 7^2. At half-order in each cyclic channel: 13^(ord/2) = -1 mod m.

Powers of 2 mod 13

2 is a primitive root mod 13. ord(2, 13) = 12 = phi(13). Every element of Z/13* is a power of 2. The ring's primes all appear as 2^k mod 13:

Prime2^k mod 13Exponent k
32^4 mod 13 = 3k = 4
52^9 mod 13 = 5k = 9
72^11 mod 13 = 7k = 11
112^7 mod 13 = 11k = 7
7-11 Swap Theorem (PROVED)
7 = 2^11 and 11 = 2^7 mod 13. The two largest chain primes swap under exponentiation by 2. 7*11 mod 12 = 5: the exponents' product gives another chain prime. Sum of all exponents: 1+4+9+11+7 = 32 = 2^5.
3 is the unique QR
Legendre(3, 13) = +1
All other chain primes (2, 5, 7, 11) are quadratic non-residues mod 13. 3 alone has even exponent.
490 mod 13
ord(9, 13) = 3
490 = 2*5*7^2. 490 mod 13 = 9 = 3^2. Its order mod 13 is exactly 3.

Arithmetic

Sum (excl projector)
58 = 2 * 29
29 is the 10th prime. The new sum encodes the old term count.
Sum of 7 primes
58
Sum of the first 7 primes. -1 + 0 + 1 = 0, so the operator sum vanishes.
Sub-sum (first 6)
41 = the 13th prime
Sum of {-1,0,1,2,3,5,7,11,13} = 41 = KEY. The 6-channel result survives as partial sum.
Sub-sum (6 primes)
42 = 2*3*7
Sum of {2,3,5,7,11,13} = 42. phi(49) = 42. The 6-prime result survives.
Count
11 = L
The protector prime. 3 operators + 7 primes + 1 projector = 11.
Primorial
510,510
2*3*5*7*11*13*17 = rad(214,414,200) = 214,414,200 / 420.

Gap Structure (PROVED)
Gaps between consecutive terms: {0, 1, 2, 3, 5, 7, 11, 13, 17}. The sequence contains its own differences -- now including 17. Consecutive differences: {1, 1, 1, 1, 2, 2, 4, 2, 4}. All powers of 2.
