Algorithm definition

The algorithm ⟨8×18×29:2535⟩ is the projection [[0, 0], [30]] of ⟨8×18×30:2535⟩.

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.
