2x2x2x2 in HSC Shape: Tesseract

Pieces: 16 4c

Permutations: \(3.3*10^{27}\)


The 2x2x2x2 (normally referred to as the 24) is a 4-dimensional twisty puzzle in the shape of a hypercube that is cut in half on each of the 4 axes.

The first official 24 solve on the Hall of Fame was done by Jay Berkenbilt in 2004 using MC4D, although it was probably solved several times before that.
