COMMENTS

Conjecture: The sequence is unbounded.
Records are 0, 18, 36, 48, 52, ... with indices 1, 14, 20, 44, 96, ...
The places of nonzero terms correspond to places of those terms of A193507 which are in A164294. Conjecture: The asymptotic density of nonzero terms is 2/(e^2+1). A heuristic proof follows from the comment to A193507 and the first reference there.
