Hmm, the answer seems to depend on whether the sequence is:

1!
2!!
3!!!

or
1!!!
2!!!
3!!!

which give the same answers up to the third value, which is all we have.

4!!!! is the correct answer.

Or written alternatively: 10^(10^(10^25.16114896940657)).

Is there a general series definition for this? I tried to develop one but my head exploded.
