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 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.

...- I would use Word 2007 to combine text and pictures. The final result would be a downloadable pdf document. An html could be produced with additional effort.
A review would be easiest in Word "track changes" mode.
Konrad wrote:
...- 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.
Konrad wrote:
- I would introduce names for all seven piece types and again, I would post a proposal for these names here and listen to your 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! :D :D

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.
