Find the remainder when

$$\sum_{r=0}^{2014} \sum_{k=0}^r (-1)^k (k+1)(k+2)\binom{2019}{r-k} $$ is divided by 64.

I think moderators closed it because, in a post, the forum wants you to explain what you've tried, Math Stack Exchange is an helping plateform, so we help you from what you tried . It is for this that they closed your question. – EDX May 13 '20 at 07:55
