comment Is this group isomorphic to $S_n\times Z_m^n$?
I think it's a good idea to link this here: Generalized symmetric group

comment Why is multiplication axiomatized?
@JyrkiLahtonen Matrix multiplication is a different matter, in my question I was thinking of real multiplication only.

comment What are some conceptualizations that work in mathematics but are not strictly true?
@Jik A triangle between three distant stars will also have an angle sum different from 180 degrees. However, I think that this answer is misleading, because the geometric principle is mathematically true - only that kind of geometry does not work on astronomical scales.

comment Is $\frac{\textrm{d}y}{\textrm{d}x}$ not a ratio?
"...just as $dx$ is not a product." You can get $dx$ by applying the $d$ operator on the $x$ differential form, and as such $dx$ is a group operation, so I think you have the right to call it a product.
