%C A359353 This is the second of four sequences that partition the positive integers. Suppose that u = (u(n)) and v = (v(n)) are increasing sequences of positive integers. Let u' and v' be their (increasing) complements, and consider these four sequences:
%C A359353 (1) u o v, defined by (u o v)(n) = u(v(n));
%C A359353 (2) u o v';
%C A359353 (3) u' o v;
%C A359353 (4) v' o u'.
%C A359353 Every positive integer is in exactly one of the four sequences. Their limiting densities are 4/9, 2/9, 2/9, 1/9, respectively.
