Algorithm definition

The algorithm ⟨8×20×32:3021⟩ is serendipitous tensor product (⟨2×5×8:63⟩ - 19) ⊗ ⟨4×4×4:48⟩ +⟨4×4×12:141⟩ +8⟨4×4×8:96⟩.

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.
