Abstract: It is an open conjecture that for any positive odd integer *m* the function

*h*. Here we show that the number of which satisfy the conjecture is at least for a positive constant

*c*. A connection between the validity of the conjecture and the diophantine equation is established. It is shown that if the conjecture fails due to an occurrence , then

*k*is greater than 17985. Finally, an analogous "" problem is settled for certain pairs .
