Below follow the 61 octominoes that occur in the 62 sets of 4 pieces (or ‘quads’) corresponding to each of the 62 nodes of the octomino network. The near equality between 61 and 62 is sheer coincidence. I regret that a previous version of this page showed only 56 octominoes instead of 61; an error. Each piece is labelled with a number. In our system, the full set of 369 octominoes were numbered from 165 to 533.
