ABSTRACT
Truncated Octahedra Besides the cube, there are only two other space-fi lling polyhedra that would appear to have much practical use as puzzle building blocks. One of these is the truncated octahedron . The blocks are fairly easy to make by starting with large wooden cubes and sawing off the eight corners using a suitable jig to hold them accurately (and safely!) in the saw (see Figure 175). To check for accuracy, the eight new faces should be regular hexagons.
