Algorithm definition

The algorithm ⟨8×22×26:2800⟩ is the (Kronecker) tensor product of ⟨2×2×2:7⟩ with ⟨4×11×13:400⟩.

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.
