The same design criteria as used for the Octahedral Cluster. The puzzle forms a triangular pyramid of twenty rhombic dodecahedra blocks. They are joined into four dissimilar, non-symmetrical pieces with five blocks each which assemble only one way and must be assembled in sequence. Stewart made 30 from rhombic dodecahedra blocks in 1979 and 25 more from edge-beveled cubes from 1981 to 1985. Number 26 in his numbering system.
