a problem in topscore says: how many arrengments can six people be seated round a circular table?
they said answer should be 120, (6-1)!=120 because you keep the position of one person constant!!! but why would you do that and the problem doesn't even tell us to do that, i see nothing special about the round table thing, I think the answer should be 720 if you do the regular permutation (6!), am i correct or are they correct??
