I don't think it can provide any information, please correct me if I'm wrong.

It provides information about edge orientation. E.g. if the edge is in the UF position, in one orientation it'll be attracted to URF but not UFL and in the other orientation it'll be attracted to UFL but not URF. On average there'll be two attracting pieces on the left side and two attracting pieces on the right side (out of UF, UB, DF, DB), but sometimes there'll be a 1-3 split or maybe even a 0-4 split.

Well, that's possible. Since the pull force is more like an average of all combined, it will be an issue if there are 0 split case (1-3 split won't matter much). Let me calculate that possibility.

That brings another point: all magnetic versions need to be investigated and verified. Not likely but possible to have such combinations, intentional or non-intentional.

Interesting problem... Cannot even imagine delegate with magnetometer examining each piece of puzzles... Even assuming the introduction of some sort of certification, the puzzle must have a design that provides unavoidable damage in case of modification.

I was able to generate a state of 0-4 split. Confirmed, should be illegal!
@xyzzy , thanks pointing it out! Glad that I posted here!

This case?

Yes, that's one example depending on how you matched up in terms of colors with magnets

I assumed this scheme (on the solved cube):

That is correct but it depends on which color part is non-magnetized. For example, I used all white and yellow, half of red and orange edges as non-magnet versions. So, if you have a state where all white or yellow is like, DF, FU, UB, BD, then, yes, one side is 0-4 state.

Non-magnet version is unstable while both magnet versions are too strong

Is 3LM feels stronger than factory 2M? I ordered LM yesterday...

Can't confirm since I don't have GTS2 LM. But heard that same magnet combinations for GTS2 for LM version.

Since I do mostly BLD, I really like extremely weak magnets just to maintain the stability.

I feel like sometime in the past couple of days, someone here (@openseas ? @mark49152 ?) gave a list of RUD G-perms that they used, but I didn't have much luck finding it. Whoever it was who had a good set of them, could you possibly repost them here? I'm thinking maybe it might finally be my solution to G-perms. I have never had even remotely satisfactory G-perms - they've always been awful - and lately they've been giving me even more trouble than usual. I've always been pretty good with RUD algs; maybe this would finally fix my G-perm problem?

 

[mark49152]

@Mike Hughey - yes I have an awesome set of RUD G-perms

PLL12 (Gd) ( D' R U R' [U' D] R2 U' R U' R' U R' U R2 )

PLL13 (Gc) ( D R'2 U' R U' R U R' U R2 [D' U] R U' R' )

PLL14 (Gb) ( D R' U' R [U D'] R2 U R' U R U' R U' R'2 )

PLL15 (Ga) ( D' R2 U R' U R' U' R U' R2 [D U'] R' U R )

I was able to find a nice fingering & flow for all of them, but since it's subjective, will leave that as an exercise for the reader

 

[openseas]

@Mike Hughey / I think we discussed about RUD V-perm not G perm. I learned G-perm from Chris Olson's tutorial, nothing special, like everybody else, most hated permutations to me, too

Okay, thanks - I did find that discussion. I think maybe @mark49152 may have just mentioned his, without actually listing them all. Mark, I'm really looking forward to seeing them!

 

[mark49152]

G-perms added. Sorry, I didn't get to it last night.

 

[pglewis]

So how about aiming to solve two cubes whilst juggling them? lol

Absolutely... if I want to turn two working cubes into zero working cubes and a replacement parts order

Thanks so much - these all seem very nice to me! Now the challenge is to actually learn them.

It might help to note they are all mirrors and inverses.

Thanks - I didn't notice at first because of the D moves being always moved to the beginning of the algs.

I think they can be done either end, but I have a preference for doing them first so that I can do them with my LH in parallel with a RH regrip, if one is necessary.
