Algorithm definition

The algorithm ⟨9×10×28:1578⟩ is serendipitous tensor product (⟨3×5×7:79⟩ - 2) ⊗ ⟨3×2×4:20⟩ +⟨3×4×4:38⟩.

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.
