Division 1 for higher-ranked participants

Division 2 for lower-ranked participants

    $\begingroup$ 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? $\endgroup$

    $\begingroup$ @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. $\endgroup$ Dec 7 '18 at 20:43
