COMMENTS
If the conjecture by Ulas and Ulas is true, then all these terms can be found from A206284 and then this is also a subsequence of A277318.

FORMULA
a(n) = A260443(A000040(n)).
Other identities.
For all n >= 1, a(A059305(n)) = A002110(A000043(n)).
PROG
(Scheme) (define (A277316 n) (A260443 (A000040 n)))
CROSSREFS
Cf. A277317 (same sequence sorted into ascending order) is a subsequence of A277319.
Differs from A277318 for the first time at n=10, where A277318(10) = 15750, a term which is missing from this sequence.
