The MagicTile groupe "elliptic sphere" is now completely solved !

The last not solved puzzle was
eb_MT_ell_sph_cube_fev111 (Super Chop)

It took me 56672 twists.

Here is an illustration of the puzzle near finishing:

In the next groupe "elliptic projective" there are 14 unsolved puzzles.

I hadn’t considered simply avoiding the broken locations, thinking I was going to need multiple versions for each rotation. Maybe I’ll see if I can just use set-up moves to use the locations that do work.

I do it always with macros. Eventually they work not at every place. In this case you must use the perhaps 50% working places.<br>

Thanks for the encouragement, Ed. I started to do it but most of my macros didn’t work and I really don’t want to do it without them. Roice understands the issue involving non-orientable puzzles but the fixes (keeping track of orientation) appear more difficult than he’s ready to take on at the moment.

    First 79 entries in the Mathologer MT Challenge Hall of Fame&#58;

    Only 2 women !?  (Marie and Marie-Chantal)

    Melinda please, change this weard statistics  ;-)<br>
    &#91;At least three M's instead of two Marie's&#93;

Thank you so much for breaking up the MT solutions wiki page! It had gotten way out of control.

      I bet Ed's 1M+ twist solution will strain a few things. It will be a great test case. Good luck Ed!

      Finally, congratulations on 100k+ video views. That happened pretty quickly. Maybe even faster than the 4D video.

      Great stuff everyone!<br>

        Super cool, both of you!  Ed, will this be the first solve you've done with &gt;1M moves?  I can't recall if there have been others. 

An update on the Mathologer video and Klein bottle challenge… Last night, the video crossed 100,000 views, which is pretty cool. We have 25 slots left in the challenge at the moment, and solutions have slowed quite a bit. They are currently coming in about one a day, so I’m guessing there will be at least a few weeks (likely longer) before it is full. I took the challenge myself (solver #49) and it was great fun - more difficult than I anticipated, with some surprising configurations. If you haven’t tried it, try it. You’ll be glad you did!

I’m doing some wiki updates right now. I’ve already split the solutions page into 3 separate pages, and am working on getting the puzzle list up to date with the current set of puzzles.

          Hi Michael,



          Do you think that Mathologer Challenge hall of fame reaches 100 items?

          You are very economic.

          I'm solving &quot;MT ell isoca fev111 (Big Chop)&quot; actually and I will reach about a million turns.

          Best regards<br>
