Et al,

	I believe that this is simply Euler's "Lucky" numbers: n such that m^2-m+n is 
prime for m=0..n-1, http://www.research.att.com/projects/OEIS?Anum=A014556 .

%N A092749 a(n) = least k such that m^2 + m + k is prime for m = 0, 1, ... n-1.
%e A092749 a(2) = 3 because 0^2 + 0 + 3 = 3 is prime, and 1^2 + 1 + 3 = 5 is 
prime, and it is the smallest number with the required properties.
