[GAP Forum] Constructing the generalised Fitting subgroup

[thefox235 .]

Dear forum,

My question is really the titular statement: could someone please
provide a routine for constructing the generalised Fitting subgroup
<https://en.wikipedia.org/wiki/Fitting_subgroup#The_generalized_Fitting_subgroup>

of a finite group G?

Provided that I have scanned the GAP manual thoroughly, this is not
already implemented in GAP, and I hope that others may benefit from
my question as well.

With many thanks and best wishes,
Stefanos
