%N A341611 Nonabundant numbers that are not primitive terms of A246282.
%C A341611 Terms k of A263837 for which A337345(k) > 1 (or equally, for which A337346(k) > 0).
%C A341611 Numbers k such that sigma(k) <= 2k and k has at least two distinct divisors d such that 2d < A003961(d). By necessity, one of these divisors is then k itself.
