Im moving from the intermideate 4 look LL to Dan Knight´s suggested
advanced 3 look LL ( orient edges, orient corners and permute all).
My questions and observations; In Jessicas page the notation
sometimes starts with (U1), (U2)or (U3).What does this mean?
Some permutations seem to make some logic sense to me and are very
easy to memorise, fo example; R²U Fs R²Bs U R² while others dont make
sense at all like R B U'B'U B U B²R'B U B U'B'. Does anyone have any
suggestions of how to approach these "illogic" algorithms?

I think a good way of memorizing is divide the algorithm
into "macros" or finger shortcuts. It also helps to follow what
happens to the first layer as you perform the algorithm. To adjust
the algorithm for your hands, do not be afraid to do some "bold"
things, such as performing the whole algorithm with a cube turned by
180 degrees or even upside down. Sometimes you can twist the cube by
twisting TWO layers with your right hand rather than just one - this
basically twists the cube by 180 degress (a neat trick) without
having the regrip the cube. I am sure you find your own tricks that
will lead to a unique style of yours.

Overall advice, try to "dissect" each algorithm and look at the moves
from different angles to figure out the best way to perform them. I
am not a big protagonist of the idea that there is just one correct
(or best) way to do the algorithms because we are all different and
we develop different twisting styles. Besides, it is soooo nice to
watch other speed cubists how they handle the cube and perform the
algorithms with ease and speed. It never ceases to amaze me to watch
others do their magic with the cube.

Pleasant memorizing wishes

I won't say those algorithms are "illogic". In fact, I think that the
permutation algorithms are very simple to learn and as there's only
13 of them (up to isomorphism or 21 if you prefer) you just have to
sit and learn them one by one. Then, you'll see some logic. You
should also read the hints in Jessica's page (a really good page by
the way, thanx a lot) about customizing the algorithms. I learned all
the orientation and permutation algoritms about three years ago. It
took me less then a week to learn the 21 cases for permutation. Then,
I broke my cube and don't touch another one in more then two years!
You know what? Even after two years, I still remember all the
permutation alg. (but I can't say the same thing about the
orientation alg.!). That's what I mean by "you'll see some logic".

When an alg. starts with U, U2 or U', it refers to the picture. It
just means that you don't have to move the U slice to fit the
pictures and then move it again. You were talking about logic, that
is pure logic!

• Thanx larrpas and jessica for your answers... perhaps (ill)logic is the wrong word but some algs seem to fit both my hands and eye more than others. I will

the wrong word but some algs seem to fit both my hands and eye more
than others. I will work on your customizing suggestions...
