m_gl_nc

synopsis: INT m_gl_nc(OP gl, il, nc)

description:

you input the group label gl to specify the group, then an object il which may be an INTEGER object, to say that you want the i-th character, and the output will be in nc. If the object il is not an INTEGER object it may be an object which labels characters in the entered group, e.g. partitions for the symmetric group. You get these objects with a previous call of m_gl_il. You will get an error for example if the INTEGER object label is to big , this means you entered a number which is bigger then the number of classes.

example:

 computes all irreducible characters of A_n
 .....
 scan(INTEGER,a);
 m_gl_alt(a,b);
 m_gl_il(b,c); println(c);
 for (i=0L;i
