One deterministic module has affine ranking function a8 and consists of 4 locations. One deterministic module has affine ranking function a17 and consists of 4 locations. One deterministic module has affine ranking function a7 and consists of 3 locations. 4 modules have a trivial ranking function, the largest among these consists of 10 locations.
