I know about euler_phi(n), but is there a command where I can a get a list or some sort of other collection for all those values where n = euler_phi(f(n))?

This seems to be rather nontrivial though I guess something like one of the many suggestions there could be implemented... at first I thought you mean the Dirichlet inverse but I guess not.
