COMMENTS

The sequence is non-monotonic. But are all the terms distinct?

A092190 is a subsequence. More precisely, a(A092189(k)) = A092190(k). - Altug Alkan, Dec 13 2015

EXAMPLE

a(1) = 4 = A001358(1),

a(2) = 10 = A001358(3) = A092192(1) = A001358(1)+A001358(2) = 4+6,

a(3) = 25 = A001358(9) = A131610(1),

a(4) = 39 = A001358(15) = A158339(1),

a(5) = 69 = A001358(24) = A254712(1),

a(6) = 58 = A001358(21) = A266451(1).
