Abelian group is a sort of stringent requirement, they probably just mean a plain monoid? After all it works for python lists, which form a non-commutative monoid:
[] + [] == []
[1,2] + [3] != [3] + [1,2]
- jessaustin 13y agoThe additional property which makes a monoid a group is the existence of inverse elements. So list is a good example for your point, because there are no "inverse lists".
