c_ijk_sn

synopsis: INT c_ijk_sn(OP i,j,k,res)

description:

computes the coefficients of the class multiplication in the groupalgebra of the S_n. It uses the method described in Curtis/Reiner: Methods of representation theory I p. 216

example:

 #include "def.h"
 #include "macro.h"

 main()
 {
 OP a,b,c,g;
 anfang();
 a=callocobject(); b=callocobject();
 c=callocobject(); g=callocobject();
 scan(PARTITION,a); println(a);
 scan(PARTITION,b); println(b);
 scan(PARTITION,c); println(c);
 c_ijk_sn(a,b,c,g); println(g);
 freeall(a); freeall(b); freeall(c); freeall(g);
 ende();
 }
