muEC::SYMF::Char2Sf – converts a virtual character into a symmetric function

The muEC::SYMF::Char2Sf function converts a virtual character into a symmetric function expressed on p-basis.

We denote by cl[part], where part is a partition, the class function on the symmetric group that is evaluated to 1 for permutations with cycletype part, and 0 otherwise.

The muEC::SYMF::Char2Sf function realizes the isomorphism between class functions on the symmetric group of degree n and homogeneous symmetric functions of degree n.

→ Examples

Call:
