The first puzzle with hybrid axis system. This combines face-turning and corner-turning hexahedron in one puzzle.
This puzzle fuses the abilities of a 2x2x2 and a Dino Cube into one puzzle. It is the first implemented hybrid puzzle with two different axis system and allows 11 different rotations if one visible piece is held fixed in space. The core of this puzzle is a 3x3x3 bandaged like a fused cube (to allow only one twist per axes). Face pieces of a rainbow (or a dino) are attached to the corner pieces.
A patent for a puzzle like this (under the name "Eleven-plane cubical") was file in 1982 and granted in 1984 to Ashley, Jonathan J.
The restrictions known from all corner-turning hexahedrons (edges can't change orientation) are compensated by the faceturns the puzzle allows. This means two arbitrarily chossen pieces can be swapped and the puzzle has 24!/24 = 25,852,016,738,884,976,640,000 permutations.
At least since 2004 this puzzle was in discussion among puzzle builders. In December 2006 the first sample of this puzzle was presented by Adam Cowan. He used a similar mechanism as the patent from 1984 described. The images presented here steem from later built duplicates of the original puzzle. The fifth image however shows a joke Adam played upon the community: He assembled one of his puzzle within a jar.
The first very stable without magnets was published by Tom van der Zanden in 2011. See image 6.
