One deterministic module has affine ranking function (((long long) -2 * op2) + 1) and consists of 6 locations. One deterministic module has affine ranking function (((long long) -2 * op3) + 1) and consists of 4 locations. One deterministic module has affine ranking function (((long long) -2 * op6) + 1) and consists of 4 locations.
