That's not a definition. I'm in front of a class asking what this function does, and I'm unable to give a mathematical definition of what Sage means by "reduction" modulo something that's not a Groebner basis. > What it does is probably do the reduction using the list in reverse order > for this case. "Probably" is not a mathematical definition. Besides, I think it's more complicated than that. Am I the only one who's regularly embarassed explaining Sage's quirks to an audience of beginners (or not beginners)?
