Minecraft wiki entry for Far_Lands, associated text: "Fake" chunks at the world boundary are another anomaly that happens at high distances. Occurring considerably past the Far Lands' beginning, they are commonly said to be a "part" or "layer" of the Far Lands. While they are among the interesting effects which can be experienced when moving high distances from the world origin, their occurrence is a distinct phenomenon, and, to an extent, actually intended. This is further reinforced by them being at a rather round number (32 million), rather than the seemingly overall arbitrary 12,550,824 of the Far Lands, or power-of-two values such as 16,777,216 where precision loss worsens.
