How to show a group is a subgroup of A_14?

Greetings,

Problem: I want to show that a simple group G of order 4*3*7*13 must
be isomorphic to a subgroup of A_14 (the alternating group of 14
letters).

Attempt: It is easy to show that there are 14 sylow 13-subgroups. And
so G act by conjugation on its sylow 7-subgroups with a trivial kernel
(since G is simple). This shows that G is a subgroup of S_14 (the
symmetric group of 14 letters). What's the next step? Thanks in
advance.
