279-element magma on F_31 x F_3^2 # Operation: (x,(r0,r1)) * (y,(s0,s1)) = (5*x + 27*y + 1 mod 31, A*(s0,s1)^T + (r0,r1)^T mod 3) # A = [[0,1],[1,1]], H = I_2 # Element index: idx(x,(u,v)) = 9*x + 3*u + v (0-based) # Inverse decoding: x = idx // 9; u = (idx % 9) // 3; v = idx % 3 # Matrix check p: A(AHA+H)=I -> True # Matrix check q: A^3+A^2 H^2+H=0 -> True
