Phew, that was fun! I've so enjoyed running the #bigmathoff, and seeing the 30 bits of fun maths that the competitors came up with.
I really appreciate all the positive comments from people following the competition.
Many thankyous to follow...

First of all, thanks to the competitors, who agreed to go along with what began as a very vague idea, and were all such good sports: @jamestanton, @Samuel_Hansen, @peterrowlett, @ColinTheMathmo, Tiago Hirth, @mscroggs, @JimPropp, @Tony_Mann, ... (1/2)
