Cubing Fun Facts

[KubikPanda]

Fun fact: the pyraminx and 2x2 were both invented before the 3x3. And both were invented in 1970.

How!? And by who!? 2x2 is just 3x3 corners w/ a fixed corner! But nevertheless, that is very interesting.

Meffert invented the pyraminx.

Some guy Larry Nicholas. His design used just magnets to hold the pieces together, and you had to grip the puzzle to make a turn. He actually sued Rubik/Ideal toys since he thought Rubik stole the idea, but since the mechanisms were very different, the court didn’t rule in Nicholas’ favor.

The number of permutations on a 3x3 is more than the number of grains of sand on planet earth.

Although how scientists have managed to determine the number of grains of sand is beyond me.

its just a rough estimate but we know its a lot less than 43 quintillion

False. He won the case against Ideal. And the appeal. And never thought Rubik stole his idea.

Really? That’s what I remember. I thought he lost the patent.

Maybe read the wiki I linked. Or Google Nichols vs Ideal.

Fun fact: The Rubik's cube is a cube

The cube is also on of several Platonic solids, which are 3D shapes that are identified based on vertices, same number and type of faces per vertice, and corners. The puzzles that fall into this category are the Cube, Tetahedron, Dodecahedron, Octahedron and Icosahedron, all of which are a twisty puzzle.

Misclicked on the "reply" button and then misclicked all of the keys on my keyboard including the shift button at the exact same time as some of the buttons in the exact right order and then accidentally misclicked the "post reply button"

Also known as a cube, megaminx, FTO, pyraminx, and whatever the icosahedron is (but that's not a WCA event anyway so who cares).

I think icosahedron is the important factor to doing a Platonic solid relay because hardware is bad and it’s hella expensive.

Aha! an opportunity to unload my inner polyhedra nerd! (I'll still keep this relevant to rubik's cubes)
now, which of the archimedean/Catalan/johnson solids can be turned into cubes?

The truncated platonic solids+the cuboctahedron and icosidodecahedron work but some have partially restricted turning
The rectified and truncated cuboctahedron/icosidodecahedron (rhombicuboctahedron/truncated cuboctahedron/rhombicosidodecahedron/truncated icosidodecahedron) also work with a few caveats
in fact, the only archimedean solids that kind of don't work are the snub cube and snub dodecahedron which can only turn on the squares, pentagons, and triangles that border 3 other triangles.

For the Catalan solids, the rhombic dodecahedron and rhombic triacontrahedron work but only turn 180 degrees, the disdyakis dodecahedron works but only on some axes, as does the deltoidal icositetrahedron. The disdyakis triacontrahedron works like a megaminx and icosaminx. Finally, the triakis tetrahedron, triakis octahedron, triakis icosahedron, tetrakis cube, and pentakis dodecahedron technically all work but of these only the triakis octahedron and triakis icosahedron have enough movement to actually scramble up.

For the Johnson solids, I'll do it later.

Actually, no, it’s a J-perm

I should add that I was trying to search up the Moyu 21x21 on my friends laptop and buy it soooooo
