0 I'm thinking about some simple counterexamples on Group Theory. "Choice a set $G$ and find a possible $1 in G$ such that $1g neq g1$ for some $g in G$ " Basically I want to find a possible neutral such that $1g = g$ and $g1 neq g$ , or $g1 = g$ and $1g neq g$ for some $g$ . Is it possible? Edit. I think I did not write correctly. I'll try to be clearer. In the definition of a group we have the axiom: "There is a $1 in G$ such that $1g = g = g1$ for all $g in G$ ." Why is necessary to verify $1g = g$ and $g1 = g$ ? I think that the reason is: in a non-group, we can find a element such that $1g = g$ but $g1 neq g$ or $g1 = g$ and $1g neq g$ . abstract-algebra group-theory
