%N Steps until an EKG sequence starting 1,2,3,...,n merges with the standard EKG sequence A064413, or 0 if the sequences never merge.

%C Are there any zeros?

%e a(5)=11 because that EKG sequence starts 1,2,3,4,5,10,6,8,12,9,15 and from the 11th term onwards it is the same as A064413.

%Y Cf. A064413, A169857.

%K nonn

%O 3,1
