Subject: Proposed scrambling notation for the physical 2^4

Date: Mon, 26 Feb 2018 01:43:52 +0000

Given that the goal is to scramble as much as possible with as few moves as

possible, and given that any I and O moves produce legal states, I propose

the following simple notation for scrambling:

The first element is (Left move, right move) which describes two twists of

the left and right halves of the puzzle. For example, (xy, z2) or (y’,

x2z). 0 means no move.

The second element is a slab move, either U, F, D or B.

The third is /, representing moving the left end cap to the right.

An example short scramble might look like this:

(x2, z)U/(xyz,x’z)B/(y’, 0)F/(x,z’)U/

Despite being only four iterations, this produces a fairly convincing

scramble. A serious scramble might be 10, 15, or even 20 of these long if

you’re that worried.

What are anyone’s thoughts on this?
