Sector 41751

From Memory Alpha, the free Star Trek reference.

Sector 41751 is a region of space in Grid 9 of the Delta Quadrant.

The USS Voyager passed through Sector 41751 in 2374, where they encountered an ancient relay station, part of a network that stretched to the Alpha Quadrant. Using the network, Voyager made contact with Starfleet. (VOY: "Message in a Bottle")

In 2376, calculations at Pathfinder Project projected that with an average speed of warp 6.2, it may have been one of the three sectors Voyager was located in, but presumably sector 41753. Lieutenant Reginald Barclay sent a message to Sector 41751 through the MIDAS array in an effort to contact Voyager anyway. (VOY: "Pathfinder")

It seems odd that after two years, Starfleet would expect Voyager to be in the same sector.
