Dec 29, 2009 at 23:43 comment added Kristal Cantwell I think I have managed to extend the result from 25 to the squares of all primes greater than 3 it is in another post.

Dec 24, 2009 at 0:24 comment added Kristal Cantwell I rewrote the proof with a value in the range q to 2q-1.

Dec 23, 2009 at 23:13 comment added Gjergji Zaimi $\frac{7}{p^2}$ can be achieved as 7/p and 1/p in series if p>7. But you are right and primes q>3 are not good as one can choose a prime q<r<2q-1. and then $\frac{r}{q^2}$ is not expressible because of a similar argument.
