Talk:Abelian sandpile model/Identity

From Rosetta Code

This second task[edit]

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)

Meaning of Identity[edit]

Surely the additive identity is:

0 0 0
0 0 0
0 0 0

One of two. The other is highlighted in the video. --Paddy3118 (talk) 14:45, 20 July 2020 (UTC)

use of the word "area"[edit]

I think a better word for a grid   area   in the task preamble would be a grid   cell.       -- Gerard Schildberger (talk) 22:14, 28 December 2020 (UTC)
