Two functions, $f$ and $g$, that satisfy the following identity: $$f(g(a_1,...,a_n), g(b_1,...,b_n),...) = g(f(a_1,b_1,....), f(a_2,b_2,...)...)$$ (notice the "transposition" of the arguments), do they possess a named and/or known property? Or as an alternative, where can I find out more about it?
(Apologies if I asked a duplicate question, but I didn't know how to search for it)
Wikipedia calls it "$f$ and $g$ commute" for multivariate functions:
