COMMENTS
It appears that the only numbers that arise twice are 1 and 49.
EXAMPLE
49 is in the list since (m=3,n=2) gives 1/1^2+1/2^2+1/3^2 = 1+1/4+1/9= 49/36 and independently also since (m=6,n=1) gives 1/1+1/2+...+1/6 = 49/20

EXTENSIONS
More terms from Hugo van der Sanden, Jun 05, 2004
The sequence of denominators could be added too. - N. J. A. Sloane.
The additional terms were calculated by Hugo van der Sanden based on the assumption that the numerator for (m=1, n=p) is always greater than that for (m=1, n<p) for all prime p - confirmation or disproof of that assumption would be helpful.
