Helicopter cube solving (and patterns)

[Portponky]

I really like that pattern :tu

 

[mrCage]

Prove that my last 2 posted patterns are not possible to achieve by using only 3 different edges although all the moving pieces can be moved by 3 edges alone (rather easy!).

Prove that even 4 edges will not suffice (harder).

Are my sequences minimal?? Use for instance ksolve!!

Nice to meet you in Trondheim Per. I didn't read this thread for a while so i missed that you came up with a improved alg for my star patter. This makes it a whole lot easier to make it

Helicopter Cube Parity?

So yeah, 2 'edges' need to be swapped. Anyone got an alg?

 

[Dene]

Could you be more specific? Perhaps a picture?

I only call pieces "centres" and "corners". I'm not sure what you mean by "edges".

You might find what you need in this thread.

So yeah, centers sorry.

I believe I posted a mirrored version of this alg in a recent curvy copter thread. Can't find it tho.

Anyway, one way to do it: DL DF RF (UR+ FL+ UF UR- FL- UF) RF DF DL

I don't quite understand the +'s and -'s in the alg.

That's jumbling. I could never understand it by seeing it written down, and I had to have someone show it to me. But I'll give it a shot anyway. You need to take the UR and FL sides, and do a turn not quite halfway, so the corners of the triangles in the FR-middle and UL-middle meet up in the UF-middle. Then you can twist the "UF" side, which has kind of become a new piece.

EDIT: If you can make any sense of what I just said you deserve an award. Here's a video: https://www.youtube.com/watch?v=NTHQ-U3aWo0

The guy in the video does it with different sides, but hopefully you can get the idea.

Ive spent the last 2 hours trying to solve this and I dont get it. It's like an impossible parity. Could someone help please?!

You could also just twist RF and resolve with an even number of RF moves

The algorithm provided by qqwref is what you need.

Sorry for the bump but Thankyou! I solved it! Thankyou so much!
