Seven CRT channels are seven interlocking gears. Each channel's modulus sets its gear size: mod 8 is the smallest gear (fastest rotation), mod 49 is the largest (slowest). As element n advances through the ring, each gear turns at its own rate. The gear ratio between any two channels = the ratio of their moduli.
Below: a side view of seven helices winding around a shared axis. Each helix is one CRT channel. Its wavelength is its modulus. Where two helices cross at the same phase = their gears mesh. All seven gears return to start simultaneously after lcm(8,9,25,49,11,13,17) = 214,414,200 steps.
Each pair of CRT channels has a gear ratio = the ratio of their moduli. Since all moduli are pairwise coprime (distinct prime powers), every ratio is irreducible. Meshing period = lcm(q_i, q_j) = q_i * q_j.
| Pair | Ratio | Mesh | Reading |
|---|---|---|---|
| mod-8 / mod-9 | 9/8 | 72 | D^3*K^2 = ouroboros cycle |
| mod-9 / mod-11 | 11/9 | 99 | K^2*L = closure + protector |
| mod-11 / mod-13 | 13/11 | 143 | L*GATE = parity pair |
| mod-13 / mod-17 | 17/13 | 221 | GATE*ESCAPE = boundary pair |
| mod-9 / mod-49 | 49/9 | 441=21^2 | (K*b)^2 = closure*depth |
| mod-25 / mod-49 | 49/25 | 1225=35^2 | (E*b)^2 = meta-meta-ring^2 |
| mod-8 / mod-17 | 17/8 | 136 | D^3*ESCAPE = bridge-transcend |
Smallest mesh: 72 = 8*9 = D^3*K^2. The ouroboros cycle (3^2 * 2^3 = 72 transitions in the 3-bit state graph). The two innermost towers mesh first.
Largest mesh: 1225 = 25*49 = E^2*b^2 = 35^2. The two depth-2 quadratic towers take the longest to align. 35 = E*b is the meta-meta-ring in Tower B.
Gears mesh when both channels return to residue 0 simultaneously. For coprime moduli q_i and q_j, this happens every q_i * q_j steps. At mesh points, both helices cross the central axis at the same height.
The 490 split reappears. DEAD channels {mod 8, mod 25, mod 49} = {D^3, E^2, b^2} (perception). ALIVE channels {mod 9, mod 11, mod 13, mod 17} = {K^2, L, GATE, ESCAPE} (strategy).
| Set | Mesh range | Count | Character |
|---|---|---|---|
| DEAD-DEAD | 200 to 1225 | 3 pairs | Wide spread, loosely coupled |
| ALIVE-ALIVE | 99 to 221 | 6 pairs | Narrow range, tightly coupled |
| DEAD-ALIVE | 72 to 833 | 12 pairs | Cross-split coupling |
DEAD channels span a 6x range in meshing periods (1225/200). ALIVE channels span only 2.2x (221/99). Strategy gears are more tightly synchronized than perception gears.
