Description of fast matrix multiplication algorithm: ⟨4×9×27:675⟩

Algorithm type

27 X^{4} Y^{4} Z^{4} + 108 X^{2} Y^{4} Z^{2} + 108 X^{2} Y^{2} Z^{2} + 108 X Y^{4} Z + 216 X Y^{2} Z + 108 X Y Z

Algorithm definition

The algorithm ⟨4×9×27:675⟩ is the (Kronecker) tensor product of ⟨1×1×3:3⟩ with ⟨4×9×9:225⟩.

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.
