Group presentation: deriving a relation I have the following group presentation: <a,b | a^5 = b^3 = (ab)^2>. Note that I'm not requiring a^5=1, just that these three elements are equal. I plugged this into GAP, and it told me the group is SL(2,5). That means b should have finite order. Is there a way, using just the two relations given, to show b^n=1 fo... 3 Feb 2010 14:01
