Dear Sage supporters, sorry, I did not find a better title for this thread.
It is about the following. If one has a cochain of degree 8, one could say (shorter) "8-cochain". John Palmieri pointed out to me that it should be "an 8-cochain", not "a 8-cochain", a fact I wasn't aware of. Can someone tell me the rule in what cases one uses "a" and in what cases "an"? E.g., one has "an" if (and only if?) the next word starts with a,e,i. And is there a function (or at least an easy algorithm that I can implement myself) that for a given integer n answers the question whether it is "an %d-cochain"%n or "a %d-cochain"%n ?
