P4M-328
From The Stargate Omnipedia
Planet in the Milky Way Galaxy, home to a feuding, technologically sophisticated people. The planet was believed to be the location of the "Key to Infinite Treasure" sought by Stargate Command.
The dial-home device for this planet was lost long ago. Archaeologists found fragments of it, and diagrams were used to create a copy on display in Cicero's museum.
