sp = scalarProduct(ch1,ch2)
Given virtual characters ch1 and ch2, the method computes the standard pairing between ch1 and ch2.
i1 : ch1 = new ClassFunction from {{3,2} => 2, {2,2,1} => -2, {3,1,1} => 2, {5} => 1};
i2 : ch2 = new ClassFunction from {{2,2,1} => -2, {5} => 1, {1,1,1,1,1} => 5, {3,2} => 3, {4,1} => -2};
i3 : scalarProduct(ch1,ch2) 17 o3 = -- 10 o3 : QQ
