Hello, I am wondering how to coerce a symmetric function in a certain number of variables into a polynomial ring with larger variables. I am getting some rather confusing output.

I want the polynomial to be a symmetric polynomial in a subset of variables in the ring R. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
