There are a total of 141 algs used in Waterman's method, provided

that you don't run into any complications. This total includes a

lot of mirrored algs.

Roughly, the method involves the following steps:

1. solve one face

2. orient and permute the remaining corners (1 of 43 algs)

Next, hold the solved face in your left hand, with the corners

solved in step 2 in the R face. The next steps are to solve the

right edge pieces (called "redges"), and orient all the middle edge

pieces (called "midges") in two algs. The M slice is referred to as

the "ring".

3. Solve 2 redges such that you leave 1 or 0 redges in the ring.

Do this by picking an alg which solves 1 redge in the ring and 1 in

the R face (1 of 6 algs), OR pick an alg which solves 2 redges in

the ring (1 of 6 algs)

4. Solve the last 2 redges, and orient all the midges in 1 alg. If

both redges are in the R face, then you have to pick 1 of 14 algs.

If one redge is in the R face, and one is in the ring, then pick one

of 48 algs.

5. solve the midges, 1 of 3 algs, which are trivial.

additional algs are included to handle situations where one or more

redges are solved by the end of step 2.

flip one redge and orient midges: 2 algs

solve one redge in the ring and orient midges: 16 algs (8 algs and

their mirrors)

if all redges are solved, orient midges: 3 algs

I think that the algs from step 3 are borrowed from the algs in step

4, but listed separately.

In addition to this set of algs, there are additional components to

the system designed to handle ugly situations such as when you have

3 or 4 redges cycled in the r face, or when you have all 4 redges in

the ring.

If you can master all of the bad situations in addition to the basic

(!) system, you should be able to solve the R face and orient the M

slice in 2 algs or processes, no matter what.

since you pretty much use only U, R, and M, you don't have to regrip

with your left hand too much (there are some algs with F moves).

Here are a few example algs from step 3 to show the basic idea. Try

doing the inverse of the algs on a solved cube to set these up.

To solve 2 redges in the ring, one at FU and one at FD (FU means

that the R facelet of the redge is on the F face as opposed to UF,

which puts the R facelet on the U face) , do this:

U2 (R) M U2 M' U M2 U (R)' U2

When you execute this alg, the redge at FU will get placed in the

hole at RU, and the redge at FD will get placed in the hole in the R

face which is turned up to the RU position with the turn (R). (R)'

is just the inverse of whatever R move you did in (R).

To solve 2 redges where one is in the ring at DF (R facelet of this

redge is in the D face), and one is in the correct hole in the R

face at the position RU but flipped, do this:

U2 (R) U' M U2 M2 U' (R)' U2

in this case, the move (R) means turn the R face so that the hole

that the redge in the ring belongs to gets moved to the RU position.

In any case its a neat but scary system.
