Now go solve — and when you hit PLL, smile. You’ve got friends in those 21 letters.
“Now,” said Sam, “what if two corners are correct, but two edges are swapped?” He showed Leo a case. “That’s an — just edges moving opposite. M2 U M2 U2 M2 U M2. It feels like a calm sigh.” pll algs
Here’s a helpful, friendly story about PLL algs (Permutation of the Last Layer algorithms in speedsolving the Rubik’s Cube). Leo was a good cuber. He could solve the first two layers with his eyes half-closed, and OLL felt like a dance he’d known forever. But PLL? That was where his solves went to cry. Now go solve — and when you hit PLL, smile
“This is an ,” said Sam. “A cycle of three corners. Learn the algorithm R’ F R’ B2 R F’ R’ B2 R2 — and watch them rotate home like a carousel.” “That’s an — just edges moving opposite
One morning, Alfie woke up across from where he belonged. Betsy was beside him, also wrong. Carlos and Dee were swapped.
