about computing the frattini subgroup :

In the gap library i have found the prefrattini method for finite solvable
group and a specific method for permutation p-groups

Does anyone have references with detailled proofs about these methods
and in general for methods to compute \Phi(G).
I know the reference of bettina about prefrattini subgroups, but i haven't
found an electronic version.

Is there a specific method for general permutation group (not only p-group) ?

thank you for your help
