%I A287116 #16 Sep 20 2017 17:28:55 %S A287116 288,336,4545 %N A287116 Nonsquare integers that cannot be represented in the form 4M-d, where (a*b)|M and d|(a+b) for some positive integers a,b. %C A287116 If there are no more terms, the Erdos-Straus conjecture would follow. %C A287116 This sequence together with the squares (A000290) and E(4) form a partition of the nonnegative integers. That is, this sequence gives nonsquare non-elements of E(4) (see Dubickas and Novikas, 2012). %C A287116 There are no other terms below 2*10^9. %H A287116 A. Dubickas, A.
