Description of fast matrix multiplication algorithm: ⟨3×18×21:840⟩

Algorithm type

336X3Y3Z2+504X3Y3Z336X3Y3Z2504X3Y3Z336*X^3*Y^3*Z^2+504*X^3*Y^3*Z

Algorithm definition

The algorithm ⟨3×18×21:840⟩ is the (Kronecker) tensor product of ⟨1×3×7:21⟩ with ⟨3×6×3:40⟩.

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.
