Great job Andras! That is quite a dramatic improvement to the previous
shortest 3^5. It seems the gauntlet has been thrown down!

When Andrey achieved his short solution, I had meant to create a shortest
category, but dropped the ball on it (sorry Andrey!). But I’ve updated the
hall of insanity pages now to document Andras’ new achievement, and all the
other current MC5D shortests. I also went ahead and added Andrey’s MC5D
solve to the list, even though it was done with a different version of the
program. Not sure what is best there, but I hope that is ok.

Also, Andras, feel free to use any of that piano music on my old home
page if you decide it would be good for the video you’re working on.

All the best,
