Ordering of Steps

As discussed in L2L4 - The lost methode? Help find it!, the ordering of {CO, CP, EO, EP} can be done in 24 ways, but some are more efficient/desirable than others. Algorithm count, move-count (for each step), and recognition are all to be noted when comparing orderings.

The reason my specific ordering was chosen was for several reasons:

  • EP is last: limited to 2-gen; fast to execute
  • CO is first: CLS, which I have already known (need to relearn) can be used as a substitute hack for the normal CO step, so I have 100 less algorithms needed to memorize. [although really, some should be optimized].
  • "only" 220 algorithms total. While this seems like a rather high number, the prospect of being to solve everything after FL with only four short sequences is intriguing. Also, compared to other orderings, this is a fairly low number.
  • The recognition for *all* of these has already been ingrained into my brain from Roux/Salvia (CO and CP individually), LBL (EO, first of my 4LLL order), and CFOP (EP5 - extended subset of EPLL).

My ordering for "Pure L2L4"

CO, which solves FL while orienting the LL corners.
CP, which solves FR while permuting the LL corners, making sure not to disturb the orientations of said corners.
then do a y2!
EO, which solves FL while orienting the remaining edges making sure not to disturb anything other than the final 6 edges which are in the working zone
EP, which permutes the final 5 edges.
