Hi Michael,

You are right. I did make a mistake by inadvertance. Thanks for correcting the error.

I will certainly try once your recomandation "hyp {8,3} 6-Color F0:2:0". But later. I’m not comfortable with the few color puzzles (3-cyle macros not constructible).

I have also a recommandation: the puzzle "eucl torus 3-6 14 color e100". You have 50% chance to not run in a parity problem. I did encounter the parity problem and it was very tricky to find a final cornerface (cf) double swap. It was necessary to see that there are 3 separated cf orbits. Then I was forced to make two setups allong the whole length of two orbits to get a special double swap (name it A). Then I did use other 2 orbits to get a special double swap B. A and B together gave me the wanted double swap.

Michael: Did you encounter this parity problem? Did you avoid it by conting in advance?

I have direct e-mail contact with Nan, Roice and Melinda p.ex. Is it also possible for you? If yes, please send me an e-mail to ed.baumann(at)bluewin.ch.

Best regards
Ed

Congrats to Dan for the 9x9x9x9 solve! You’re crazy!

12 more hyperbolic puzzles done, so I have under 150 to go. I’m going to move on to IRP and Skew puzzles next. There are more hyperbolic puzzles that I know how to solve, but that are very big (500+ pieces up to a maximum of 2464) and I don’t want to lose motivation.

By the way:
(1) {8,3} 6-Color F0:2:0 is a very interesting puzzle. I won’t give any hints, but anyone who hasn’t solved it, I recommend giving it a try.
(2) I think I found a mistake in the high score list, Eduard Baumann has a {8,3} 6-Color E0:1:0 V0:0:1 solve listed, but actually, the link and date and movecount are for {10,3} 6-Color E1:0:0 V1:0:0. Have you solved that {8,3} puzzle? It has 616 pieces so it would probably have a much larger movecount.

{5,4} 12-Color (Non-Orientable) E0:1:0 - 1034 twists
