%N A359277 Intersection of A026430 and (1 + A285953).
%C A359277 This is the first of three sequences that partition the positive integers. Taking u = A026430 and v = 1 + A285953 (which is A285953 except for its initial 1), the three sequences are (1)  u ^ v = intersection of u and v (in increasing order); (2)  u ^ v'; and (3)  u' ^ v.  The limiting density of each of these is 1/3.
%e A359277 (1)  u ^ v = (6, 9, 10, 15, 16, 19, 24, 27, 28, 31, 36, 37, ...) =    A359277
