Another geometry-defying design which allows only jumbling turns.
The solid itself is beautifully regular. It is a true square antiprism which consists of two squares and eight regular triangles.
The geometry on the other hand is not that easy to understand. There are eight possible twists, one for every corner of the solid although no move leaves the shape unchanged. Only jumbling turns are possible for this puzzle.
