What are the next four numbers in the sequence 1, 2, 3, 4, 5, 3, 7, 4, 6, 5, 11, 4, __, __, __, __?

When does the number 12 first appear in the sequence?

I had some computer assistance, so I will not give the answer away yet.  I think that 12 first appears as term 41472 in the series.  Of course, I may have made a mistake.
