Algorithm definition

The algorithm ⟨8×9×18:840⟩ is the (Kronecker) tensor product of ⟨2×3×3:15⟩ with ⟨4×3×6:56⟩.

Algorithm description

maple tensor representation (compressed by bzip2);
maple evaluation scheme (compressed by bzip2).

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.
