This puzzle implements a subgroup of the 3x3x3, namely (UD', L, Ls, Fs).
The two holey edges behave coupled to each other. In addition the Up- and the Down-side are coupled with the rod visible through the holes, too. See image 5.
It was inspired by an idea from Bram Cohen and was meant to proove the difference between a slice move and an opposite-faces-move.
This variant has 1966000148840448000 permutations which equals (U, D, L, Ls, Fs) the version without slice move.
Edge length: 60 mm
Weight: 114 grams
