in a 2009 paper, dave benson gave a description in purely algebraic terms of the mod $ p $ homology of $ \ omega ( bg ^ \ wedge _ p ) $, when $ g $ is a finite group, $ bg ^ \ wedge _ p $ is the $ p $ - completion of its classifying space, and $ \ omega ( bg ^ \ wedge _ p ) $ is the loop space of $ bg ^ \ wedge _ p $. ...
