Hello everybody,

I'm trying to proof a certain conjecture I invented myself for quite a long time now but in fact I have no idea how to do this.

The conjecture says:

For the function

with

a_1,a_2,a_3,a_4,... <d

and

exists no natural result exept form 1, 2 and 4.

I tried so hard to find an argument that proves this assumption but it didn't work so far. Has anybody an idea?

I would be really glad if there was somebody who could help me.
