The J is pretty messy and hardly general! But normal stuff...

My approach that suits J ways of solving a much wider class than just this type
of problem. Relies on 2 pretty simple independent concepts.
1. I define a "perfect function" as simply a function that returns all of its
arguments. This is suitable to processing by many J techniques such as ^: t
maybe that’s not a question for this forum but
since you already mentioned a couple of systems:
How do GAP and Sage compare in this regard?
I’d have expected them to be competitive in
this field as well.
