Algorithm definition

The algorithm ⟨20×24×25:6466⟩ is serendipitous tensor product (⟨5×12×5:204⟩ - 42) ⊗ ⟨4×2×5:32⟩ +⟨16×2×5:126⟩ +2⟨4×6×5:90⟩ +16⟨4×4×5:61⟩.

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.
