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?

(In reply to re(3): When 12 appears by Steve Herman)

10! is 3628800, which is not divisible by 512. 512 is 2^9, but 10! has 2 as a factor only 8-fold.
