A Rank 18 Waring Decomposition of sM〈3〉 with 432 Symmetries

 

Abstract

The recent discovery that the exponent of matrix multiplication is determined by the rank of the symmetrized matrix multiplication tensor has invigorated interest in better understanding symmetrized matrix multiplication. Author present an explicit rank 18 Waring decomposition of sM3 and describe its symmetry group.
