Pieces  :  4 

The four puzzle pieces are made up of fourteen rhombic dodecahedra. There are at least there ways to fit all of the pieces into the box so the pieces are flush with the top of the box.
For a second problem, set the box aside and make a pyramidal pile with a square base.
For a third problem, use three of the four pieces to build a triangular pyramid.
Stewart made 30 from 1984 to 1985. Number 61 in his numbering system.
