Puzzle, Truncated Cube

This puzzle is in the shape of a truncated cube, with its eight corners sliced off. It was made in Taiwan and received in an -open box that looks like a Rubik's Cube.
The eight corners of a cube are sliced so the puzzle has eight silver faces that are equilateral triangles and six octagonal faces of the same colors as the traditional Rubik's cube, blue, orange, green, red, yellow and white. The Diamond (see 2006.0061.09) is also a truncated cube. The slices in the Diamond are larger so the six faces do not join opposite vertices of the corner squares but, instead, join the midpoints of the center edge squares producing six squares rather than six octagons.
This puzzle is among Rubik’s Cube related items from the Cube Museum, which operated in Grand Junction, Colorado, from 1988 to 1991. For more information about the Rubik’s Cube and other twisting puzzles that use the same or similar mechanisms see 1987.0805.01.
