4x4 Parity algs

• 4x4 adjacent center swap: u’ R2 u d R2 d’
• 4x4 opposite center swap: Rw2 U2 D2 Rw2
• 4x4 OLL parity <[ r U2 x r U2 r U2 r’ U2 l U2 r’ U2 r U2 r’ U2 r’ ]>

2x2 algs

2x2 OLL

• R U R’ U R U2 R’
• R U2 R’ U’ R U’ R’
• F (R U R’ U’) (R U R’ U’) F’
• F (R U R’ U’) F’
• F (R U’ R’ U’) (R U R’) F’
• (R U R’ U’) (R’ F R F’)
• R2 U2’ R’ U2’ R2

2x2 PBL

• Use PLL if one side is solved
• R2 F2 R2 swap both diagonals
• R2 U’ B2 U2 R2 U’ R2 swap both back adjacent
• R’ U R’ F2 R F’ R swap top adjacent (put bar on back), bottom diagonals
• R2 U R2 U’ R2 U R2 U’ R2 swap bottom adjacent (put bar on left), top diagonals
