Pyraminx Crystal

[mrCage]

Hi

See the link below for the notation in use.

U and D are opposite faces. T1 - T5 are the adjacent layers in clockwise fashion around the U layer. Similarly B1 - B5 are the adjacent layers of D in clockwise fashion.

Notation: T1++ moves T1 layer 2 steps clockwise, T1-- 2 steps counterclockwise etc.

For the first case: (adjacent edges)

1: T1- B2- (setup)
2: T5+ T2- T5++ T2+ T5++ (edge 3-cycle)
3: B2+ T1+ (unsetup)
[9 turns, 11 steps]

For the second case: (spread edges)

T1++ (setup)
T5+ T2- T5-- T2+ T5+ (edge 3-cycle)
T1-- (unsetup)
[7 turns, 10 steps]

That second 5-moves 3-cycle is quite nice. I easily found it last night after you made me search for it and it's pretty useful for my LL edges method I showed in my video, saving a few moves.

Gotta try your first one at home where I have the puzzle, I'm too tired to visualize it mentally.

Per, why not place B1 opposite to T1, it would make it easier to remember the order of the sides then.

god I want one of these, but I just don't have the 42 bucks on me. Congrats on the good times Stefan.

I just got a 3:38 single. I'll do an average later because I don't ahve time to right now.

I did it like that to avoid showing the dodecahedron from 2 perspectives. But yes you're right, that would be less confusing i guess. I think the face names (letters) are quite good anyway. Not too intuitive but easy when you get used to it. Anyhow, the diagram was purely instructive, to make the algos absolutely clear to anyone :rolleyes:

"Adjacent U perm" can also be done in 7 turns (8 fifth turns).

Hi Stefan.

Care to share? (in the same notation as mine). Or you will make me look for it ?

You'll find it. I'm actually shocked we haven't found it earlier. I can even parenthesize it two different meaningful ways, i.e., I have two approaches for finding it.

Hey, I'm bumping an old tread... but I just recently got my crystal

I found you got two puzzles in one here. You can take out all edges and it still works, (better than with the edges actually!) So if you "mode" your crystal like that you get something that can be treated as the 2x2x2 version of the Megaminx, a puzzle with only corners to solve. Try it =)

I did one try for a full solve, got 1:51.23 ... need more practice, my best for the whole puzzle with edges is just above 7 minutes.

NOTE: be careful to align the last turn before the next one, else you can probably kinda easily break the puzze.

If someone can take a picture of a no edge minx, please do and post it here because it looks really weird

Kenneth... the 2x2 version of the minx is just the impossiball. It already exists and has been produced by meffert's for a while.

I beg to differ. It's called the kilominx.

The puzzle doesn't seem that easy to break to me. The way the inner structure is conceived with misalignments you will rather get big ppps (if you force on an inner edge it will pop but not break).

I beg do differ...

if you look at the thread (and the one he links at the beginning), you'll see that they say this puzzle is just like an impossiball, which is older, so Dan is probably right...

OK, but, if you got a crystal you don't need to get one if you like to try it, just pick the edges out.

TMOY, ok it may pop instead, I wrote that just in case.
