I just read what appears to be theanswer on http://quora.com: https://www.quora.com/How-do-you-know-if-a-Cayley-table-define-a-group-operation/answer/Justin-Rising?srid=uDgC (Justin Rising's answer). (Always check wikipedia first.) |

I'm actually asking for something like a test that you would apply to a single number to know whether it's prime: isPrime(7). I'm new to sage, I admit. _To me_ it seems reasonable to be able to pass a table to a constructor and then ask when it satisfies the group axioms. But I would also admit that this doesn't seem to be the way sage is intended to work. |
