“…While there are algorithms for computing a ν λ,µ (see for example [4,23]), no satisfying combinatorial description has been found. In this section we describe two rectangular symmetries satisfied by the plethysm coefficients.…”

“…We do not apply it directly, as it relies on 'nested inverse Kostka numbers'. As explained in [Yan98,Yan02], the computation of those, although possible in many cases, is a nontrivial task. For this reason, we introduce one more change of basis of symmetric polynomials, relating our results to transportation polytopes.…”

“…Numerous algorithms have been developed for computing the Schur expansion of a plethysm (most recently [5,6,25]), and several specific cases and extremal results have been obtained [2,3,4,15,22,26]. But an explicit combinatorial formula for the full Schur expansion of an arbitrary plethysm s λ [s μ ] has proved elusive.…”
