Algorithm definition

The algorithm ⟨6×30×32:3400⟩ is serendipitous tensor product (⟨2×5×8:63⟩ - 19) ⊗ ⟨3×6×4:54⟩ +⟨3×6×12:160⟩ +8⟨3×6×8:108⟩.

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.
