Littlewood-Richardson Calculator
The Littlewood-Richardson Calculator is a program designed to compute Littlewood-Richardson coefficients. This program is written in the C language to make the computation as efficient as possible. The program can compute single Littlewood-Richardson coefficients, products of Schur functions, or skew Schur functions. In addition it can compute products in the small quantum cohomology ring of a Grassmann variety. The software package also includes a program that performs fast computation of the more general multiplicative structure constants of Schubert polynomials.
