I’ve been talking with Remi some off the group list, but let me
take the chance to congratulate him here too. Great job! The writeup was
very entertaining and I especially liked the cliff hanger last night ;) I
will of course have to attempt to reclaim the crown, but Remi, I think
you’ll be safe for a while!

I thought I’d mention one small thing regarding something you wrote near the
end. In doing my last solution, I did try to place as many 3C colors at
once as I could (not just one with each sequence). There seems to be a
balancing point though, because this approach can start turning into the
situation where preliminary moves alone require so much complexity that they
exceed the length of just using extra main sequences.

Anyway, congrats again Remi!
