The 144 symmetries of the Littlewood-Richardson coefficients of $SL_3$

Emmanuel Briand, Mercedes Rosas

Published 2020-04-10Version 1

We compute with SageMath the group of all linear symmetries for the Littlewood-Richardson associated to the representations of $SL_3$. We find that there are 144 symmetries, more than the 12 symmetries known for the Littlewood-Richardson coefficients in general.
