cube theory

========== Introduction ========== In cubing, the term "metric" means a system for counting moves. The most famous and common one by far is OBTM (outer block turn metric, also known as HTM, half turn metric) as it is the wca's official metric for NxNxN puzzles. Other famous metrics include QTM...

Uh-oh. There's nothing here about using ChatGPT to generate 3x3x3 solution methods. You've just been Surprise Challenged by Chris Hardwick! There's only one Golden Rule: Surprise Challenge Golden Rule) Do the challenge listed below right now. Clarification of the #1 rule: Don't warm up...

Hello guys. I have been for a while playing arround with a challenge that I have called the "Man's number" challenge (by Man, here I mean the "human beeing" meaning of the word, women are also very welcome to the challenge!! :)). The porpous of the challenge is following: try to determine the...

not sure if this thread belongs in the help section. I was really wondering for a long long time about how methods are created. i've heard stuff about alg gens and stuff but how do people come up with these ideas?? Pure creativity or something like that?

Hey guys, is this method already existing (Maybe it’s just a sub-method of Roux. I tried to find a way to avoid CMLL intuitively.)?: CMLL-Skip-Method (Proposer: StarStarSpace, 2024) or 1/162-Method (because in one out of 162 solves you could’ve just done Roux with a CMLL-Skip) Steps (42 – 55...

What is the reason that doing only R and U moves preserves corner permutation? Well I guess "preserving" corner permutation isn't really the correct term; the more accurate question would be out of the 720 possible CP states with 6 corners, why are only 120 of them reachable using <R, U> moves...

In a 3x3x3 cube solving process, using cfop method, cross and 2 or 3 slots have been solved, and you can only see three faces of the cube(normally front right, and top), according to current information you get, is there a programming algorithm to say a corner or an edge can be determined or...

1. The ideal answer I am looking for is if it's possible to turn each layer only once clockwise at a time, and that the opposite layer can not be turned immediately after. We are looking for an alg to describe U' in terms of U, D, R, L, F, B, i.e., clockwise quarter turns without repetition and...
