Commentary

Extracted from the N=336 high-density record. After multiplying by 29 and translating, the seed splits into seven +7 pairs over the exact core C={(0,2),(0,4),(1,1),(1,4),(2,2),(5,0),(5,1)} in (Z/7)^2. Self-lift C to an exact 49-point code in (Z/49)^2 and optimize independent GL2(7) coordinate systems for the two base-7 digits; this orientation is wrap-free at q=118, N=49q.
