Records are 0, 18, 36, 48, ... with indices 1, 13, 19, 43, ... .

The places of nonzero terms correspond to places of those terms of A194658

which are in A164288. Moreover, for n>=1, places of nonzero terms of A194659 and A194186(n+1) coincide. This means that these sequences have the same lengths of the series of zeros.

Conjecture 2. The asymptotic density of nonzero terms is 2/(e^2+1).
