%N Consider the EKG sequence (A064413) started at n instead of 2; a(n) = number of steps before sequence merges with A064413, or 0 if the two sequences never merge.
%C For the purpose of this sequence, ignore the initial 1 in A064413 and imagine that it begins with the 2.
%C The upper points appear to occur at primes, the points just below the upper points at twice primes.
%C Are there any zeros?
