Description
This is a little vague - should it also be for SR, not just polynomial rings? But it seems like a reasonable request on sage-support:
Hi, I would like to know if there are any function that says if a polynomial is or not symmetric (like: 'is_symmetric'), so Mathematica have this kind of function. http://en.wikipedia.org/wiki/Symmetric_polynomial Thanks!

Note: See
TracTickets for help on using
tickets.
The following works (at least in sage-4.4.4):
If someone wants to make a top level function like that suggested in the initial post, a design discussion should probably happen on sage.devel or sage.combinat.devel first.
I'm changing the component to combinatorics since that's where tickets related to symmetric functions usually live.
