From my experience in #1102, it seemed to be worth wile, to compute the S in H = AS by computing the hnf H and then solving H = AS. At least for random square matrices this is much faster, than taking H, T = hnf_with_transform(A) and inverting T.

Additionally, for random square matrices larger than 100×100, it even becomes faster to compute T via S.
