rubiks 20070912-5 (armhf binary) in ubuntu focal

 This package contains several different Rubik's cube solvers,
 either useful directly on the command-line or through sagemath.
 .
 Michael Reid's "optimal" uses pre-computed tables to find an optimal solution
 to the 3x3x3 Rubik's cube.
 .
 Dik T.Winter's "dikcube" uses Kociemba's algorithm to iteratively
 find a short solution to the 3x3x3 cube.
 .
 Eric Dietz' "cubex" has fast non-optimal solver for the 3x3x3 cube.
