    $\begingroup$ I certainly appreciate you keeping on top of this particular contest. Is it typically a monthly challenge, lasting roughly 10 days per month, from start to deadline? $\endgroup$ – amWhy Dec 7 '18 at 18:55

    $\begingroup$ @amWhy It seems that way. I became aware of this contest since I have encountered attempts to cheat in past months while reading combinatorics questions. $\endgroup$ – N. F. Taussig Dec 7 '18 at 20:43
