Algorithm definition

The algorithm ⟨6×20×32:2336⟩ is the (Kronecker) tensor product of ⟨2×5×4:32⟩ with ⟨3×4×8:73⟩.

Algorithm description

These encodings are given in compressed text format using the maple computer algebra system. In each cases, the last line could be understood as a description of the encoding with respect to classical matrix multiplication algorithm. As these outputs are structured, one can construct easily a parser to its favorite format using the maple documentation without this software.
