 OFFSET 1,1 COMMENTS This sequence consists of the primes p (not 5, 13, or 37) such that p == 1, 3 or 5 (mod 8). The density of these primes is 0.75. - T. D. Noe, May 21 2004 Primes of the form a^2 + b^2 + c^2 with 1 <= a <= b <= c. - Zak Seidov, Nov 08 2013 LINKS Amiram Eldar, Table of n, a(n) for n = 1..10000 EXAMPLE 101 is a term since 101 = 64 + 36 + 1 = 8^2 + 6^2 + 1^2.
