It's on the Apocrypha II disk.

The Precipice Subsector does have a map and data - there is also an Aramat
system map.  Aramat itself is "one parsec spinward from Palmyra", though the
subsector mpa shows it to in fact be one parsec to trailing!

Some of the other worlds in the Precipice subsector include Trent, Tappon
and Dalaan (the three high pop - capitalised - worlds, also the type A
starports) and a Red Zone at Zephyr.

Given the confusion over directions, the Palmyra in the Solomani
Confederation is presumably pure coincidence...

Probably a co-incidence, there was a lot of data generation since 1984, and while it's getting easier to find the more obscure stuff, there was no real opportunity over the years to weed out duplicates, or to make sure generated maps were fully consistent with published material.

Precipice SubSector, sounds like another candidate for being placed 'far away' on the Traveller Map.
