Convention:Function composition

This article is about a convention that is followed in this wiki. The aim is that every page on the wiki follows this convention unless explicitly stated otherwise on the page; however, in practice, this may not have been implemented
Also see switching between the left and right action conventions for background on the differences between various conventions.

In Groupprops, the notation $f\circ g$ always denotes $g$, followed by $f$. In other words, if $g:A\to B$, and $f:B\to C$ are maps, then $f\circ g$ denotes the composite map from $A$ to $C$.

This convention for function composition also explains the corresponding convention for group action.
