GAP subgroups know its parent, which in the case of permutation groups amount to knowing the domain of action. Sage ought to follow the suit, IMHO On May 21, 6:36 am, Jason B Hill wrote: > This is definitely an example of where Sage and GAP differ in their > approaches, but this is more about sub

Hi Jason, Thanks for your comments. I was mulling some commentary on your previous post about permutation groups, but my comments are just applicable in this case, so here goes. My main interest in Sage is its use in my teaching. GAP is a perfect example. I've always felt that the syntax and l
