your discussion was very interesting and, in fact, it also helped me to understand that I formulated the problem incorrectly.

I guess I was wrong in letting f be an endomorphism.
f is simply supposed to be a function (defined in all G) and with the property we mentioned in respect to H.

but then I guess not much can be further discussed(???)
