• Smallest k such that circle x^2 + y^2 = k passes through exactly 4n integer points.at n=27A018782
• Least number which is the sum of two distinct nonzero squares in exactly n ways.at n=13A093195
• a(n) is the smallest nonnegative integer k where exactly n ordered pairs of positive integers (x, y) exist such that x^2 + y^2 = k.at n=28A328151
• Let n = p_1*p_2*...*p_k be the prime factorization of n, with the primes sorted in descending order. Then a(n) = 5^(p_1 - 1)*13^(p_2 - 1)*17^(p_3 - 1)*...*A002144(k)^(p_k - 1).at n=27A340388
