COMMENTS
A number m belongs to this sequence iff A196047(k) < A196047(m) for all k<m.
FORMULA
a(n+1) <= 2*a(n); this follows from the fact that A196047(2*m) = A196047(2) + A196047(m) = 1 + A196047(m); thus if m belongs to this sequence then either 2*m does or there exists a smaller number that does.
CROSSREFS
