NMCLL

NMCLL was first mentioned by Gilles Roux for use in the Roux method. A recognition table was partially developed.

The steps are:
- Find the orientation of the L/R stickers.
- Find the orientation of the stickers that should be oriented to the U layer.
The table wasn't yet 100% developed. There were still 15 missing patterns.

James Straughan completed the NMCMLL table in October, 2006

A new recognition method for NMCMLL was developed by James Straughan in April, 2010

The steps are:
- Find the orientation of the L/R stickers.
- Check a pattern by looking at pre-determined sticker locations.

Another recognition method for NMCMLL was developed by James Straughan and Tim Mosher in December, 2021.

This recognition method was developed to be an all in one solution for CLL, NMCLL, and CCMLL recognition.
