Pyraminx puzzle for X Window System

The original puzzle has 9 triangles per face size = 3 and has period 3 turning i.e. the face or points turn in 120 degree intervals. The puzzle was designed by Uwe Meffert and called the Pyraminx. This has 2^53^86!/2 or 75,582,720 different combinations. Another puzzle Senior Pyraminx 3x3x3 exists only on paper, it has period 2 turning i.e. edges turn with 180 degree intervals but the corners would fall off unless it had some tricky mechanism. This may be the same as the Master Pyraminx which has 446,965,972,992,000 different combinations. Another puzzle which was not widely distributed, the Junior Pyraminx and similarly the Junior Pyraminx Star, a octahedron formed by two tetrahedra, this has 7!*3^6 or 3,674,160 different combinations, has 4 triangles size = 2 per face and at the time I designed this computer puzzle thought that it had only period 2 turning i.e the edges rotate. It turns out the puzzle has a period 4 turning edges turn with 90 degree intervals which makes it analogous to the 2x2x2 Rubik’s cube. This puzzle makes various non-tetrahedral shapes. The puzzle contained here has no period 4 turning flexability.
