Table of n, a(n) for n=1..58.

FORMULA

j is in this sequence if for some integer k > j, j^2 + k^2 = c^3.

EXAMPLE

2 is in the sequence because 2^2 + 11^2 = 5^3;

7 is in the sequence because 7^2 + 524^2 = 65^3;

1 is not in the sequence because 1^2 + k^2 is not a cube for any k > 1;

3 is not in the sequence because 3^2 + k^2 is not a cube for any k > 3.
