A077059 Numbers j such that j^2 + k^2 is a cube for some k > j. 4

%I #15 Sep 23 2018 21:01:53

%S 0,2,5,7,9,10,16,17,18,26,30,35,36,37,38,40,44,47,50,51,54,56,58,60,

%T 65,72,73,74,75,80,82,88,95,97,101,102,106,107,115,122,128,130,135,

%U 136,140,142,143,144,145,146,150,154,164,170,182,187,189,190

%N Numbers j such that j^2 + k^2 is a cube for some k > j.

%C The values of minimal k in A077060 and A077061. The values of corresponding c in A077062.

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

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

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

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

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

%Y Cf. A076600, A077059-A077062.

%K nonn

%O 1,2
