%I #4 Mar 31 2012 10:22:16

%S 1828,3332,4100

%N Positive numbers which have more than two representations (m,s) as a difference s^2-m^5, m>=1, s>0.

%C This sequence is a subsequence of A177770.

%C Contains also 10993 and 53668, not necessarily as the next terms. [_R. J. Mathar_, May 23 2010]

%e a(1)=1828 = 98^2-6^5 = 186^2-8^5 = 90298^2-96^5.

%e a(2)=3332 = 58^2-2^5 = 66^2-4^5 = 190^2-8^5.

%e a(3)=4100 = 85^2-5^5 = 1026^2-16^5 = 1790^2-20^5.

%Y Cf. A152412, A177760, A177761, A177763, A177764, A177765, A177766, A177770.
