(and other questions) %A Igor Rivin %J Mathematics %D 2013 %I arXiv %X We discuss the question of how to pick a matrix uniformly (in an appropriate sense) at random from groups big and small. We give algorithms in some cases, and indicate interesting problems in others. %U http://arxiv.org/abs/1312.4607v1
