Face Turning Rhombic Dodecahedron Part 1: Help me with this parity!

[@gusbert]

Amazing as always SAV, your analysis is the best part of your videos.

Красивая головоломка, надо будет купить себе такую. Всем добра:)

Like with Benpuzzles, and also the Flower Copter, you could have very well built it just off kilter. However, on Curvy Copters, I believe there is a way to swap just two corners. My initial though, since at this point, it's just the two 'corners' that need to be swapped, maybe your corners could be one swap, and two 'center' pieces be the second swap.

[@SuperAntoniovivaldi]

You can swap two corners, but this leads to a 180 degree rotation of the center edge. In that way the parity is conserved. On this puzzle, the equivalent piece to the edge are those top and bottom corner pieces, so I can't swap the two edges without swapping the corners. Good thought, though!

SuperAntonio, I was wondering if you could help me in something. I recently got a CubeTwist bandaged 3x3 kit and am completely mesmerized with the combinations however idk where to start. I've tried a few commonly known ones like the bi-cube, nate's bandaged cube, the big block, traffic jam, and the bandaged bridge cube. I was wondering if you can visually recommend some other variants of bandaged cubes.

Maybe if you can come up with an algorithm that swaps two big corners and two pettels and then you could do that algorithm to finish that step

[@SuperAntoniovivaldi]

Not a bad thought, but the swaps of the petals aren't equivalent to swaps of the corners...

[@jacusjoe]

How did you get yours to turn so well! Mine is so stiff even after loosening the screws

It's not the mass produced version

I think it would've been better to compare the FTRD to the Curvy Copter 3, rather than the regular one. The homologies add up a lot better: CC3 corners are like the Tri corners on the FTRD, CC3 centers are like the Quad corners, and the 4 petals that surround the CC3 center are like the Triangle pieces on the FTRD.

[@GreenArt4]

I've watched your CC3 tutorial, and you already seem to have an algorithm to rotate the small petals, which would work just fine on the FTRD triangles :)

[@tabris1135]

I have to agree on that

[@SuperAntoniovivaldi]

Ah, very resourceful of you! I can tell you've been paying attention ;)

[@NDPuzzles]

This doesn't even look too complicated when it comes to the number of pieces. But if even you are struggling with it I assume this is a very hard puzzle :D

Hi, I hope you check my comment however the video itself is 7 years old. So my problem is I succeeded to move every corner in place, no parity, but two big corners, three-sided ones, are turned in place. One is clockwise, other is opposite. I tried to move one around and put in place just the right orientation but at the and I have two turned corners again. Do you have any idea? Thanks in advance.

Hi, It seems I found an algo, it works in both cases (the unoriented pieces are next to each other or opposit), so I went on. The trick in nuthshel is: move one arount the four-colour-corner, make the threecycle, then move back and make again.

Perhaps you have built your color scheme on the wrong faces? I know this can happen with the Helicopter cube as well. Great puzzle by the way.

[@SuperAntoniovivaldi]

You'll notice something very similar with the flower copter ;)

[@devin_t4032]

Is it possible that you could rotate a face 360 degrees and resolve the corners? I always think of parity problems as "option" problems. I could have solved it another way.... kind of like your false equivalency methodology.

[@SuperAntoniovivaldi]

Ah, very close!

[@devin_t4032]

If you think of parity that way it seems to make more sense.... hopefully that helps someone else out there struggling with how to deal with parities. Anyways. Huge fan! Thanks for showing so many awesome puzzles that hopefully will be mass produced.
