Description of fast matrix multiplication algorithm: ⟨2×2×28:98⟩

Algorithm type

14 X^{2} Y^{2} Z^{2} + 84 X Y Z

Algorithm definition

The algorithm ⟨2×2×28:98⟩ is taken from:

Hopcroft and Kerr 1971 [DOI]

Algorithm description

maple tensor representation (compressed by bzip2);
maple LRP 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.
