Pieces:6

The four corners puzzle is a variation of the Diagonal Star. All six pieces are identical, except in the example shown, four different woods are used to make the puzzle a little more difficult and prettier. The assembled shape is an intermediate between the first and second stellation of the rhombic dodecahedron and has tetrahedral symmetry. Like its predecessors, the four corners is the foundation for many more complicated variations. Stewart made 200 from 1971 to 1975. Number 6 in his numbering system.
 
A plastic version called Aries was made and sold by Skor-Mor.
