  • Ticket #18514 – Description

    v197 v198  
    55In the experimental version 2.1.5, I have improved the computation of Poincaré series, depth and filter degree type (the latter now uses a Hilbert-driven computation of Gröbner bases in elimination order, which works since in that setting the Hilbert function is easily available), and I added new functionality related with nilpotency.

    2725Many tests have changed, since the ring presentations of the computed cohomology rings, specifically for non-primepower groups, have changed. I do not fully understand ''why'' they changed. but it seems that it is a consequence of changes in Singular. The changes did (of course...) not affect the isomorphism types of the rings.
