Dear sage-support, Is there a preferred built-in method for invoking elementary symmetric functions in Sage?
The best that I could turn up was something like the following: sage: e = SFAElementary(QQ) sage: e([2]).expand(3) x0*x1 + x0*x2 + x1*x2 That is very nice, but when I tried to automate some constructions (in Sage 4.5.3), I ran into the following sort of problem: sage: for i in range(3): ... print(e([i]).expand(3)) Traceback (most recent call last): ... AttributeError: 'list' object has no attribute 'parent' Is it obvious what I am doing wrong or how I might work around this issue? Thanks for any suggestions that you can offer.
