Super cool, both of you! Ed, will this be the first solve you’ve done with >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>
