Talk:Abelian sandpile model/Identity

This second task

My bad! I created this task without first checking for similar on RC. Only when adding the task did I do the search and found the other, so took a look and decided to tuck this in as another sandpile task as it deals with the idea of identity sandpile from the Numberphile video and a specific 3x3 grid as well as sandpile addition. --Paddy3118 (talk) 15:16, 15 July 2020 (UTC)
