How do most people do the M-layer? My GHII requires me to do r and R'. Does it need more lube so I can do it with one finger?

gon, please don't bump after only one page, or after only three hours. Be patient.

There are two ways. The most common way is to use your middle finger (either hand, I believe left hand is more popular). The middle finger goes on the BD cubie and just slice it through. For M (reverse direction) people just do r' R.

The other way is for M2. You can either do ring-middle trigger, or the way a few people do it is something like this: L (l' M'). Basically, bring back the left face (or right face if you prefer right hand), put the middle finger on the UB cubie, and then drag it back around to perform an M2.

I'm sorry, I was afraid people wouldn't see it cause it was on the last page.

Thank you Dene!

Maru lube or CRC for MF8 Megaminx?

Lol, I sprayed each piece individually with CRC, and now it's too slippery. Should probably play with it a while more to wear it out a little. Thanks for all the answers.

I'm sorry to bump but I just wanna share how I do it. For M I do r' R or I use my finger to reach the BU sticker and push. M' I use my left ring finger. M2 trigger is done with ring then middle finger of rapid pushing of the BD sticker.

What's Ghosthand's official site?

I don't believe that Ghosthand has a website. Many of the manufacturers do not.

Really? According to speedcubes.net, Ghost Hand is also known as TND, and this is their website.

Is there a written tutorial for Pyraminx Oka?

I want to get a square 1
Cube depot sells it for 10 dollars, but there is also a super square 1 for 9.50

is it a bad idea to go for the super square 1 if I don't know how to first solve a regular square 1.

 

[hawkmp4]

You'll need to know how to solve a regular Square 1 first. I would get a regular Square 1 and see if you like it.

How would I prove that a 2-gen algorithm cannot cycle 3 corners?

Your proof would have to be a fallacy though.

Oh? Why's that?

what cubesmith shade is similar to that of the vcube blue?

How would I prove that a 2-gen algorithm cannot cycle 3 corners?

I recall seeing a page on this subject...it was mostly a proof that if a cube was scramble using <R,U>, and two corners were placed with only <R,U>, that the other 4 corners would have correct permutation.

I was actually thinking about something similar and wanted to find that page; if I find it I will post back here.

Thanks, that's the kind of thing I'm looking for.
Also, does it mention that <R,U> cannot change orientation of edges? I know it's more obvious than corner permutations, but I'm interested in how "rigorous" proofs are written.

Anyone got a good pure adj 2 flip <MU> alg?

M' U' M U' (M' U')3 M U' (M' U')2

Or U if you prefer

Thanks

Learnt alg in less than half a minute and after 3 tries, I can execute it sub 2

The common definition of edge orientation is that an edge is oriented correctly if, when placed in its correct position with <L,R,U,D>, it is oriented correctly. A consequence is that <L,R,U,D> can't change the orientation of an edge- it would be a horrible definition for edge orientation if the process for determining edge orientation could change edge orientation. (Heisenberg Uncertainty Principle for the cube? xD)
I don't know if that's satisfying enough for you. Ryan Heise's site has a bit of information on it. This thread (http://www.speedsolving.com/forum/showthread.php?t=21630&highlight=proof+permutation) is a good read, also. Post 27 has some good info.

THAT'S A BINGO!

I found it. I should've thought to check Jaap's site immediately. That should give you what you're looking for. The thread that lead me there (http://www.speedsolving.com/forum/showthread.php?t=17908&highlight=proof+permutation) is also good reading.

I recently finished learning all my PLLs and my times have levelled out over the last few weeks (80% of solves are between 22 and 25 secs). This is the 1st time this has happened since I started F2L about 5 months ago.

Is this normal and is it likely I will start losing time off my average again soon?
I solve around 100 cubes a day and this is only likely to increase.

Just practice a lot

 

[~Adam~]

A lot more than 100 a day?
I solve at least 50 a day at work but I can put more time in at home if necessary.
