One deterministic module has affine ranking function (length1 + ((long long) -1 * i)) and consists of 4 locations. One deterministic module has affine ranking function null and consists of 4 locations. One deterministic module has affine ranking function null and consists of 5 locations. One deterministic module has affine ranking function null and consists of 3 locations. One deterministic module has affine ranking function null and consists of 13 locations.
