Commentary

Let M = F_11 x F_7, let Q = {1,3,4,5,9}, c_i = 1 if i = 1, and c_i = 0 if i != 1, and define (i,s) * (j,t) = (6i + 6j, H_ij(s,t)), where H_ij(s,t) = 4s + t + c_i, if i = j, t, if j - i in Q, -s - t, if j - i notin Q union {0}. First coordinates are calculated modulo 11, second coordinates modulo 7.
