This version of the main SARAh web page calculates possible couplings between irreducible representations of G(k) – for each irreducible representation of G(k) the symmetrized Kronecker power is calculated up to order 8 and tested against a linear coupling term from a second irreducible representation.
(One piece of advice – when you click evaluate, it will look like nothing is happening for a few seconds.)
