Nature of problem:To find the number of states and index classes for unitary group representations as a function of the labelling frames and distribution of numerals. | ||

Solution method:Find the Kostka numbers using matrix inversion. | ||

Restrictions:Usable for any unitary group for which time and storage are available. | ||

Unusual features:Some subroutines are in Fortran. Lists are used to find frame ordinals. Permuted strings of indices are used in finding the determinant. | ||

Running time:Through S(3), SU(4) : 0.93 s. |
