|Out of universe information|
P3X-234 is a planet in the Milky Way galaxy which held a Stargate. In an attempt to escape from Thors Replicator-infested starship—the Biliskner—SG-1 beamed the Stargate from Earth up to the Biliskner where Teal'c manually dialed P3X-234. The team managed to get to P3X-234 just before they were overrun by Replicators and some time there before moving on to P4X-234. (SG1: "Nemesis")
Behind the scenesEdit
The address of the planet is visible when Teal'c manually dials the 2nd, 3rd and 4th symbols.
