A penalty of 2 seconds given when a cube is put down with 1 layer past the first penalty line, but not past the second line. The line is where the slit between the FU edge and the FRU corner goes past that of FU and FLU, and was implemented by Tyson Mao, a board member of WCA, who wrote the official WCA rules.

3-Cycle
1. A permutation involving 3 pieces.
2. To cycle (permute in a cyclic manner) 3 pieces.

Solving the last layer in 3 steps. Usually refers to the intermediate method to Fridrich, in which orientation is done in two steps (corner edge or edge corner) and permutation is done in one step.

4-look Last Layer
A primitive last layer approach and the first step to learning Fridrich. Usually edge orientation, corner orientation, corner permutation, edge permutation, in that order.

6 edges 4 centers
The finishing step for many traditional corners first methods and also Gilles Roux's method. Can be approached in numerous ways.

Start with a solved cube perform R U R' U R U2 R' U2 (same as the first but without the U2 at the end). Done 5 more times returns to the solved state. (David Salvia)

Seven Sins of Speedcubers
Accoding to Duncan Dick, they are
"1.. Taking a cube to bed with you

2.. Solving a cube when you should be working or studying
3.. Intolerance of those who can't solve the cube
4.. Frustration at the stupid things people say when they find out you can do the cube
5.. Deliberately popping during a slow solve
6.. Talking cube jargon to those who have no way of udnerstanding
7.. Teaching other people to solve the cube"

i just wanted the newbies to have an easier time to view
these terms and have the basics here at home
(i mean PCA) and
no more need to view other pages right?

Hope this becomes a sticky.
