What would be general term for the following sequence:

$1, 13, 205, 4245, 114345, 3919860, 167310360,...$

I tried looking on oeis, It appears this is OEIS A059355:

No recurrence or formula is given.

I tried to induce, but couldn't find an answer. Any help will be appreciated. Even a recurrence would do.

Apparently this series represents coefficients from fractional iteration of $e^{x} - 1$

What does this represent? or is it just a brainteaser? –  anorton Jun 13 '13 at 1:05

Similar post on MO was closed, turned up after googling for those values. –  Calvin Lin Jun 13 '13 at 1:08

@swapedoc Can you check if this sequence is also from codechef, since it's generated by this user? –  Calvin Lin Jun 13 '13 at 1:15
