Sector 184 was a region of space.
In 2365, Jean-Luc Picard requested a listing of all deep space launches from Earth that were to or near to the Ficus sector. The USS Enterprise-D computer listed ship missions to the region proximate to the Ficus sector, between sectors 184/02 and 185/38. Upon seeing the listing of launches, William T. Riker said that there were no records of missions for the Ficus sector. (TNG: "Up The Long Ladder", okudagram)
