# M2/R2

From Speedsolving.com Wiki

M2 and R2 are blindsolving methods developed by Stefan Pochmann. M2 is for solving edges and R2 is for solving corners. The methods solve one piece at a time, using conjugates composed of M2 or R2 to swap the contents of a 'buffer' location with a target location.

NOTE: r2 and R2 are slightly different. r2 (with lowercase r) is for 4x4 cubes. See external links.
