L5EP 4U + 1D​

First Development​

L5EP was first proposed by Mike Bennett in December, 2005 on the Speed Solving Rubik's Cube Yahoo group [1, 2]. Mike Bennet developed the algorithms and placed them on a website in January, 2006 [3].

Other Developments and Popularity​

Second Development​

In mid-2006, Michael James Straughan independently had the same idea and developed the algorithms for use in the MI1 method [4].

Popularity​

In 2008 Kennth Gustavsson developed a naming system for each case [5]. Within Kenneth's thread, Straughan developed and posted an arrow-based representation image using Kenneth's naming scheme and the algorithms previously developed by Straughan [6, 7]. The image and the wiki page helped L5EP gain some popularity, eventually making its way into various methods. Some example methods include ZZ-Portico, Hawaiian Kociemba, Mehta, and Squall.

Alternate Naming Scheme​

An alternate set of names for each case was developed by Andrew Mahovich and Cubingcubecuber [8, 9].
