evaluation of character of symmetric group.

asked 2016-06-14 02:37:37 +0200

This post is a wiki. Anyone with karma >750 is welcome to improve it.

I am writing a code in sage where I am using character of Symmetric group. I want to evaluate the character of symmetric group on certain conjugacy classes. While I know the command for defining character as below.\

G = SymmetricGroup(3)\

rho = SymmetricGroupRepresentation([1,1,1])\

chi = rho.to_character();

I want to find chi([2,1]) that is to evaluate chi on the conjugacy class of type (2,1). Any help please ?

Like that:

sage: G = SymmetricGroup(3)
sage: rho = SymmetricGroupRepresentation([1,1,1])
sage: chi = rho.to_character()
sage: chi(G([2,1,3]))
-1

This is explained in the doc.
