 Relisted to generate a more thorough discussion and clearer consensus.
 * Keep. Google scholar finds about 20 hits for "commutative magma" (a better title; it should be singular not plural, and the non-associative part is redundant else it would be a semigroup), mostly by groups of researchers independent of each other. That's weak but I think it's enough for WP:GNG. —David Eppstein (talk) 06:35, 17 March 2016 (UTC)

 * Keep. I agree with David, this should be called a commutative magma. I think the term commutative non-associative magma probably came from the related notion of commutative non-associative binary operator. Here is a section in Bourbaki that defines a commutative magma and discusses associated properties like centralizers. Bourbaki, along with the Gscholar references David mentions, is enough notability for me. The nom has a point, though. I was unable to find an RS discussing rock paper scissors as a commutative magma. It appears in the folk literature, like stack exchange, but I cannot find an RS. Without an RS, the RPS material may need to be cut. --Mark viking (talk) 18:59, 23 March 2016 (UTC)


 * Keep and rename to commutative magma as suggested above. Gandalf61 (talk) 13:42, 29 March 2016 (UTC)
