Post date: Dec 21, 2014 4:29:4 AM

There is a new version of the maple code (version 1.2), with a new procedure matqBruhat(n,S,r) for computing quite efficiently the number of rank r n-by-n matrices over F_q with support contained in S. It uses intersection with Bruhat cells. This is in the "Code maple" page.
