A260124 The second infinite sequence starting with a(0)=0 such that A(a(k)) = a(k-1) for all k>=1, where A(n) = n - A037445(n) (cf. A260084).

Comments

The second infinitary analog (after A260084) of A259934 (see comment there). Using Falcao's method (2015) one can prove that such an infinite sequence exists.

All the first differences are powers of 2 (A260123).

See also comment in A260084.
