Commentary

Monogenic cyclic-affine Eq677 magma of order 949. On Z/949, in construction labels, x*y = 373x + 180y + 1 (mod 949). Element 0 generates the whole magma; there are 864 generators and 1 idempotent element(s). For any element r, the generated submagma has size 949/gcd(949, (373+180-1)r+1). Both coefficients are units modulo 949, so this is a quasigroup (left- and right-cancellative); its fiber matrix is all ones. The affine Eq677 conditions are ab(1+b^2)=1, a+a^2*b^2+b^3=0, and (b^2(a+1)+b+1)c=0 modulo n. These hold for the displayed parameters. Independently checked all 900601 Eq677 instances, all 949 Eq255 instances, and full set closure from generator 0 directly in the saved table. This is not a counterexample to Eq677 => Eq255. Found while enumerating monogenic cyclic-affine models of orders below 1000, working upward in order. These are standard affine constructions, added to fill gaps in the database. Construction labels may differ from the server canonical labels. Computed with OpenAI Codex working with dwrensha, 2026-09-27.
