Borg spatial designations

The Borg use a numerical system of spatial designations to identify regions of space, with matrix or unimatrix being the largest division, followed by (spatial) grid, and then octant.

This grid system was later adopted by the crew of USS Voyager after it was introduced by Seven of Nine into the ship's stellar cartography database. Starfleet also used grid references when they were referring to Voyager's position in the Delta Quadrant.
