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

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).
