A 4x4x4 solid can be filled with three copies each of three heptacubes, with one cube left unfilled. Here we restrict the heptacube to be a solid heptomino.

Below is a catalog of the heptomino triples for which solutions exist. These are qualified by the placement of the monocube, which can be in one of four placements, arbitrarily labeled here as A, B, C, or D. For example, the first set shown below, the combination of three astronaut-, three bulldozer- and three chair-heptacubes, has only one solution, and that has the monocube placed at A. Similarly, three cobra-, three music- and three notch-heptacubes can only be solved with the monocube at D.

Many sets can be solved with the monocube at different places. For example, three bulldozer-, three cleaver- and three spatula-heptacubes can be solved with the monocube at any position, but has the nice property that the solution is unique for each such placement.

The catalog links to solution drawings whenever there are three or fewer for a particular monocube placement. For example, to see the solutions for three bulldozer-, three cleaver- and three spatula-heptacubes, click the solution drawings link. In the bottom half of the linked window you will see a frame for each solution. Within the frame you can click on the next (or previous) link to add (or remove) a piece from the drawing.
