 A285882 Numbers which are twice a U(2,4) number but not the sum of two distinct U(2,4) numbers. 1

 OFFSET 1,1 COMMENTS The sequence could also be described as numbers that have no representation as a sum of two distinct U(2,4) numbers, but have a "pseudo-representation" u + u, where u is in U(2,4). a(10), if it exists, is larger than 10^8. - Giovanni Resta, May 02 2017 LINKS Table of n, a(n) for n=1..9. EXAMPLE 188 is in the sequence since it can't be written as the sum of two distinct U(2,4) numbers A048951, but 188 = 94 + 94, where 94 is in U(2,4). CROSSREFS Cf. A048951.
