%N A159082 Numbers whose squares added to 7! are prime.
%C A159082 1) Necessarily a(n) is not divisible by 2, 3, 5, 7.
%C A159082 2) Sequence is conjectured to be infinite.
%C A159082 3) It is conjectured that an infinite number of terms are primes.
%C A159082 4) Note that sequence contains a(k), a(k+1) prime twin pairs, first are (59,61), (461,463), (827,829), (1319,1321).
%C A159082 5) It is conjectured that an infinite number of a(n) are squares, first are 121=11^2, 169=13^2, 529=23^2, 841=29^2, 961=31^2, 1681=41^2, ...
%C A159082 6) m!+k^2=n^2 are the generalized Brown number triples (m,k,n).

%F A159082 7! + a(n)^2 = prime.
%e A159082 1) 7!+1=71^2, (7, 71) is the largest (of three) Brown pairs; Erdos conjectured that there are no others.
%e A159082 2) 7!+3^2=5049= 3^3 * 11 * 17, 7!+5^2=5065 = 5 * 1013, 7!+7^2=5089 = 7 * 727, 7!+9^2=5121 = 3^2 * 569, 7!+11^2=5161 = 13 * 397.
%e A159082 3) 7!+13^2=5209 prime, so a(1)=13.
