Random Cubing Discussion

[Tim Major]

Can anyone post some sample solves or something for the Nutella pyraminx method? I watched the tutorial, but still don't really understand what you have to recognize, or what's being solved when.

Ok, I just looked at the first 2~ minutes of the video then, with your post in mind.
It's basically Oka, but different first few steps (unless I'm understanding wrongly). It seems very similar to Oka, Oka style, just it does avoid bad cases, and does more at once.

Scramble: U L R U L' R' L R B' R L' (I just took the tips off)

Youtube Oka
1. B' L'
2. R Dw' R' Dw' R
3. L' R' L R
This solves the top 2 edges around a corner, then orients centres, then places the 3rd top edge. It now leaves the bottom 3 edges to be solved.

Advanced Oka
1. L' R
2. (U) R Dw' R L' R' L R
3. (U') R U R'
In this case the last 3 edges skipped, it's basically inserting 1 edge solved, then the second edge, so that it would be right with 3 moves (into the other slot). This is "solved" for now. You then orient the centres, find the 3rd edge and do R U R' to simultaneously solve the 2nd and 3rd edge. This is to be used in combination with Oka, youtube style, and you look ahead to see which method would work better, and to make sure the 3rd edges isn't in the 2nd edge's spot.
Another example of Oka, Oka style to clarify.

Spoiler

U L U R L' B' U L U' L' B
1.
2. U' L U L' U' R'
3. Dw L' U L

Now back to the original scramble, and using the Nutella method.

Nutella Method
1. B U L U R' L (B, U')
2. Dw' R' L' R L' R L

I rotate to put what the aim of the first step is. One of the top edges solved (at the back), and the other 2 swapped, but on the right colour.

You then finish just like Oka.

Notation: Normal Pyraminx notation, with (U) = rotations with a U turn, followed by the bottom. Also, Dw' = turning the bottom layer like a 3x3.

Ahh, I think I see now. I was trying to also pair up the B corner, and also wasn't sure whether you had freedom to place any two of the three front edges in those two slots. The video doesn't really make it clear, but I think I could actually do some Nutella solves now (once I learn the algs).

advanced Oka should be:
1(Forcing an easier center case than just L): (U) L' U R
2+3: U' R L' U' R'

(R u R' u') (R U R' U')x3 6 Edge Flipper

Sorry if I'm not the first to create this.

(R u R' u') (R U R' U')x3 6 Edge Flipper

Sorry if I'm not the first to create this.

I think you mean (R u R' u') x3 (R U R' U') x3

Yup, and Stefan posted that in the BLD algs thread.

I lold, then I got sad

Funny thing is, if you do the OLL parity fix (4x4) on 3x3, it has the exact same effects except for the single edge flip (duh).

r2 B2 U2 L U2 R' U2 R U2 F2 R F2 L' B2 r2

Besides being impractical and irrational, it's awesome!

I'm pretty sure that the r is unnecessary. They can just be R2s.

Did he give up on 1LLL? He was toying with the idea, I thought.

So, this just randomly occurred to me (that's why I'm posting it in the Random cubing discussion thread), what if there was a thing where you had to reassemble a 3X3 as fast as possible? It would be kind of pointless, but maybe a little fun.

Has anyone else noticed that you can recognise colors better in daylight than in artificial light, artificial just seemt too "yellow".

Ah, I see. Thanks for that.

You can get white lights.
