Non-RC Eq677 magma, size 275 = 11*25, unglued version of the recipe (no element e): carrier F_11 x Z/25, base law i*j = 6i+6j mod 11, off-diagonal (i,s)*(j,t) = (i*j, t) if j-i is a nonzero square mod 11 else (i*j, -s-t mod 25), and EVERY diagonal fiber a copy of the non-RC size-25 seed magma#d732efd172ca4d7b9967999fff8c2c19229e25d23884fce7dbc53f3cb456aad4. Unlike magma#dc2f657e34e8de11126c640cda74edb6 (same recipe with only one non-RC fiber), the fiber matrix here is normal (rank 265): uniform seeds restore the symmetry. Not simple (quotient F_11).
