Minimal Octa is a deep-cut skeletal puzzle with an octagonal symmetry. It has the same geometry as Ben Streeters Gemstone II. All moves a jumbling moves. It is a minimalistic puzzle in the same vein as Minimal Twist, Minimal Jumble and Minimal 7x7x7. This implementation highlights this jumbling-only geometry on a Jaap's sphere. A related puzzle is Minimal Hex. The rainbow color scheme was suggested by Jared McComb.
