Oh no (alas). This solver only works with TetraVex-type puzzles, that is puzzles for which you cannot rotate the pieces. My algorithm only permutes the pieces, like a 256-card deck. But if someone finds a way to transform the Eternity II puzzle to a TetraVex (the hardest part, IMO), then a solution can be found with this program... in the blink of an eye. ;)
