I looked around again recently, and I'm really almost certain that the Gap isn't Earth West 2,217,644 - maybe the person who changed the title of the page made a mistake? It's always refered to as "around two million worlds West of the Datum".
And the same guy made "The East Gap" page, stating that it was located a similar distance from Datum Earth (one step out) as the West Gap. I've checked, and the only two chapters that mention the East Gap (41 and 54 of TLW) don't mention the "one out" thing, only that they're similar distance.
So, if we want to change the name, what should it be called? "Earth West 2,000,000 Plus Change (The Gap)"? And change the GapSpace earth to "Earth West 2,000,000 Plus Change (Gap East 1)"?
Or change "Earth West 2,217,644 (The Gap)" to just "The Gap"?
What do you think?
