Random Cubing Discussion

Interesting... is God's number 20 for 3-gen (both RUL and RUF)?

How many RUL positions are there? RUF?

How many RUL positions are there? RUF?

RUL: 8! * 3^7 * 10! / 2 = 159,993,501,696,000
RUF: 7! * 3^6 * 9! * 2^8 / 2 = 170,659,735,142,400

The reviews on The Cubicle of the moyu 13x13 are rather weird...

RUL: 8! * 3^7 * 10! / 2 = 159,993,501,696,000
RUF: 7! * 3^6 * 9! * 2^8 / 2 = 170,659,735,142,400

Would it be feasible for a computer to check these for optimal solutions in their respective 3 gens?

 

[qqwref]

Sure, finding optimal solutions is quite doable. It's a bit much to do a God's Algorithm table without some cleverness, though.

I've never sub-1.5ed any PLL even once, and I'm almost sub-15. Is that normal?

Idk if its normal, but my LL is ~6.25 and I'm almost sub-16 so I'm right there with you.

Maybe you use roux?

I wouldn't say it's normal but it isn't exactly abnormal either. I average almost sub 17 and I just got a 1.43 U perm on my third try.

 

[GuRoux]

Maybe you use roux?

then h and z perm should be under.

 

[Randomno]

then h and z perm should be under.

Depends how long you've been using M slice and double M slice.

Nope, that's very weird. How much do you try? Give the <MU> U perms a go. They're the only PLLs I can sub 1.

 

[guysensei1]

Ok on a more serious note I could sub-1 J, T, H, U and A perms before sub-15...

Work on your TPS I suppose. Just spam the algs.

If you do, then you'll be sub-15

What is God's number for Roux L6E if:
1)We allowed only <M,U> to be used? STM here.
2)We allowed all faces of the cube to turn? HTM here.


EDIT: Unrelated topic, but, Shengshou, why don't they just spend that little extra to get better screws whose heads don't degrade after a few turns?! It really annoys me and I am afraid of tensioning any Shengshou cube.

For the "EDIT" part --- Yeah, I know Right. I ruined one of the screw .Thank god I did not loosen it too much ortherwise I would not be able to screw it back in

For question 1: 20 STM or 23 SQTM.

2) Good question, not sure if there's an easy way to do this, since it can't be done in ksolve and there would be 184320 positions to check (so you'd have to generate them all and feed them through a solver). If it helps, the antipodes listed above all have 15f* solutions (e.g. R F' B' U R' L B' R2 F' L2 B U' D R' D2 (15f*)).

Trivia question that nobody will get: Out of those who do NOT have an official 3BLD mean, who has the fastest official 3BLD single?

Who are some really fast Yau5 users? I know of Justin Thomas and Pedro Roque only.
