Hang on, let's get the roolz again please?
Is it scramble and add OR delete (one only)?
Or can you scramble and add AND delete, or in other words substitute (which is what we've done several times)?

If it's only the former then we're stumped with COMPACT
But since we used the latter to get from APOMICT (COMPAIT, COMPAT, COMPACT) presumably we can use the latter?
