One could argue that this question should be posted on the maths forum, but I see it so frequently in physics that I find it more productive to ask it here.
In a symmetry group, do we have freedom of choice of how the group is going to act in the coordinates? Or is the way the group act on the coordinates imposed on us by the group itself?
An example of what I mean: do I have the freedom to identify a group of order 2 as the responsible for rotations around say, X axis, or this same group I could say that is the group of reflections in say, XY plane?
