A285882 Numbers which are twice a U(2,4) number but not the sum of two distinct U(2,4) numbers. 1
4, 188, 192, 388, 408, 1356, 1424, 4620, 14892 (list; graph; refs; listen; history; text; internal format)

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

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.
