Professor Pyraminx Help

The Professor Pyraminx can be reduced into a Pyraminx... Well, a shallow cut Pyraminx, but solving it is identical. And yes, the Royal Pyraminx can be reduced into a Pyraminx.

Hi everybody..
Today I tried to solve my Prof Pyraminx.. i almost completed the edge grouping, but I came across this situation:

I tried and tried but I wasn't able to swap those 2 pieces.

Does anyone have a solution for that?

You need to look at that situation slightly differently. Assume that the yellow-blue and the blue-green middle edge are correct and solve all the edge-wings to them. Instead of needing to swap two middle centers (which can't be done) you need to swap two pairs of edge-wings. You can do it in two 3-cycles.

Thank you, with that little tip I was able to complete the solve.

With a little bit of searching effort you could have found the answer to your question in several posts of this very thread (e.g. in bmenrigh's post from Aust 15th) :wink:

I got mine about a week ago, and I solved it without any guides (except for the 3-center swap guide in this thread)!

So, here's my method:
- Pair three edges.
- Arrange the three edges so that they make up one face - it doesn't need to be solved.
- Pair the other three edges by flipping one edge at a time, then turning it at the appropriate depth.
- Solve the centers. It's a bit inconvenient doing these after the edges are paired...
- Solve as Jing's Pyraminx (which I did figure out quickly, including the center-swap), use appropriate parity techniques.

I have posted this on this other thread:
viewtopic.php?f=1&p=266876
Maybe, I can find here two or three volunteers as proof readers?

Especially looking at my solution (reduction to Jing's Pyraminx) would be helpful.
My English is getting checked, already.

I have made the tutorial I had been talking about in the previous post.
If you want to contribute something, you can contact me via PM and you would get two links, for a Word 2007 file and an identical pdf file. Be warned, though, that the document has (due to many pictures) 25 pages.
Some updates on my project

....I believe that writing a good tutorial for the naive reader

I mean the "not so experienced twisty puzzler"

(I assume that Uwe is looking for this) is some challenge and a lot of effort.

If really nobody else is volunteering, I could start something, but I cannot promise anything, when I will be able to finish it.

Ready for review, September 27th

Here are a few guide lines, how I would do it:
- I would describe a reduction method, where the Professor Pyraminx is reduced to a Halpern-Meier tetrahedron (Jing's Pyraminx). I would not describe this last part, besides the situation where you need a 3-cycle of centres.

I have included the Jing's Pyraminx part as well.

- I would use photos and Gelatinbrain 5.1.10 producing pictures and diagrams

I have not used Gelatinbrain, because I wanted less confusing diagrams, showing unimportant pieces (do not care at the current stage) in grey colour. Therefore, I have used Coreldraw a lot and that can have caused errors.

A review would be easiest in Word "track changes" mode.

...- I would introduce a notation for face and vertex moves and provide picture sequences for important move sequences (bhearn, if you read this, you see that I try to avoid the word "algorithm" :lol:

)I would post a proposal for this notation here and listen to your feedback.

This is my try getting feedback.

First of all, Rox and Geert, please check with Uwe, if he can wait for another two months or so.

I have not heard from Uwe, if he is interested, but I want to finish the tutorial in a decent quality, in any case.

You can download my Professor Pyraminx tutorial

Thanks to bmenrigh and Burgo for your great reviews!

Please, remember that the target audience is the not so experienced puzzler.

Anyway, I want to bring it to your attention that it exists.

Professor Pyraminx Tutorial

I found this to be the best video tutorial out there. He also does tutorials for the morphinx puzzles all the way through 7x7.
