## Group Operation Symbol

I think it would be better to leave group operation symbol "empty", as this is the usual style for non-abelian groups and $\circ$ might lead to a confusion with function composition.

- You can use the dot if you like, but leaving the operation symbol empty is too confusing. In order to understand exactly what is going on, it is in fact optimal to use a different operation symbol for all operations involved, so it is clear which operation applies to which. As it stands, the juxtaposition technique makes it difficult to see what is going on. --prime mover (talk) 08:39, 5 May 2020 (EDT)
