Description of fast matrix multiplication algorithm: 〈4×21×21:1155〉
The algorithm 〈4×21×21:1155〉 is the (Kronecker) tensor product of 〈2×3×3:15〉 with 〈2×7×7:77〉.
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.
