	~~[[Image:skewbdiamond-2.jpg\|frame\|right\|The Skewb Diamond]]~~		Alyson is what my husband loves to call me but I don't like when people use my complete name. I've usually loved living in Alaska. Since he was eighteen he's been operating as an info officer but he plans on changing it.

	~~[[Image:skewbdiamond-3.jpg\|frame\|right\|The Skewb Diamond, slightly twisted]]~~

	~~The '''Skewb Diamond'''~~ is ~~an [[octahedron]]-shaped puzzle similar~~ to ~~the [[Rubik~~'~~s Cube]]~~. ~~It has 14 movable pieces which can be rearranged~~ in ~~a total of 138,240 possible combinations. This puzzle is the [[dual polyhedron]] of the [[Skewb]].~~

	~~== Description ==~~
	~~The Skewb Diamond has 6 octahedral corner pieces and 8 triangular face centers. All pieces can move relative to each other~~. ~~It is a~~ '~~'deep-cut'' puzzle: its [[Plane of rotation\|planes of rotation]] bisect it.~~

	It is very closely related to the [[Skewb]], and shares the same piece count and mechanism. However, the triangular "corners" present on the Skewb have no visible orientation on the Skewb Diamond, and the square "centers" gain a visible orientation on the Skewb Diamond. Combining pieces from the two can either give you an ~~unsolvable [[cuboctahedron]] or a [[compound of cube and octahedron]] with visible orientation~~ on ~~all pieces~~.

	~~== Number~~ of ~~combinations ==~~

	~~The purpose of the puzzle is~~ to ~~scramble its colors, and then restore it~~ to ~~its original solved state.~~

	The puzzle has 6 corner pieces and 8 face centers. The positions of four of the face centers is completely determined by the positions of the other 4 face centers, and only even permutations of such positions are possible, so the number of arrangements of face centers is only 4!/2. Each face center has only a single orientation.

	Only even permutations of the corner pieces are possible, so the number of possible arrangements of corner pieces is 6!/2. Each corner has two possible orientations (it is not possible to change their orientation by 90° without disassembling the puzzle), but ~~the orientation of the last corner is determined by the other 5~~. ~~Hence, the number of possible corner orientations is 2~~<~~sup~~>5<~~/sup~~>.

	~~Hence, the number of possible combinations is:~~

	:~~<math> \frac{4!\times 6!\times 2^5}{4} = 138,240.</math>~~

Wilber Berryhill is the name his mothers and fathers gave him and he completely digs that name. My working day job is an info officer but I've already utilized for another 1. I've usually loved living in Kentucky but now I'm considering other choices. To climb is some thing I truly enjoy doing.<br><br>My website; tarot readings - [http://alles-herunterladen.de/excellent-advice-for-picking-the-ideal-hobby/ alles-herunterladen.de],
