Polar LSLL is an LS method where the corners and edges are oriented and positioned to the left and right sides as a first step or before arriving at LSLL. This creates a DR like state on the left and right layers.
In the basic variant, the last pair is solved while orienting the corners so that the L/R colors face L/R. In more advanced variants, the edges are also positioned to L/R. Then the LSLL polar DR state is permuted. This last slot method is useful for producing a domino reduction state. The idea for this came about in 2010 after the development of NMLL.
