The history of the Far Lands in Java Edition can be split into three main sections:
Types of Far Lands
Combination types
A world with far lands can be divided into multiple parts depending on how many axes one given noise generator is overflowing on at a given time at that position. In the diagrams below, normal terrain where nothing is overflowing is marked in gray, one overflow in light blue, two overflows in magenta and three overflows in lime. This can be extended to an arbitrary whole number of dimensions, although there are currently no modifications that allow for 4D or above terrain generation.

Facial / "Edge" / "The Loop"
The most commonly depicted form, this is the result of an overflow on only one axis. On a 2D plane, there are four different overflows possible, corresponding to the four edges of a square. In 3D space, there are six different overflows possible, corresponding to the faces of a cube.
Edge / "Corner" / "The Stack"
These are the result of an overflow on two axes. On a 2D plane, four cases of this are possible, corresponding to the vertices of a square. In 3D space, there are twelve such possible intersections, corresponding to the edges of a cube.
Vertex / "The Abyss"
A rarely encountered type, this can only be encountered with three axes overflowing at once, which is effectively impossible in any version without mods. There are eight possible regions for this case, corresponding to the vertices of a cube.
