Minecraft-related numbers

Minecraft is a sandbox building game which the player interacts with and transforms the surrounding environment of cubes as they see fit. It has gained popularity due to the very large number of possible structures that can be built in the game with only a few block types, making it like a huge online Lego box.

The following list is comprised of numbers related to Minecraft, and a brief description after each number to explain it's significance.

Class 1 Numbers
16  There are 16 pixels to the edge of a standard block in Minecraft using the default texture pack.

256  The default build height limit of a Minecraft world.

1536  The number of pixels visible on the surface of a standard block in Minecraft using the default texture pack.

65536  The number of blocks contained in a normal Minecraft chunk with a default build height limit.

Class 2 Numbers
12550821  Prior to Minecraft version Beta 1.8 there would generate layered terrain in stark contrast to the normal terrain after one journeyed 12550821 blocks from the X/Y coordinate (0,0) on either the X or Y axis. These were called the farlands and were removed later in the game.

30000000  Prior to Minecraft version Beta 1.8 the game would generate 'fake chunks' beyond this limit on the X/Y axis that the player could no longer stand on.

2147483647  Past this limit blocks will not be rendered and the game will crash if the player attempts to manually traverse this limit.

262144000000000000  This is the number of interactive blocks in a Minecraft World, including air blocks and assuming a normal height limit.

2^1024  This is the true height limit of Minecraft, for beyond this point the game will not consider your position on the Y-axis as a valid number. Here is a video in which the height limit is discussed.

1.47*10^11097 The number of unique possible textures for a single block in a 16x16 texture pack. This number has been derived with the knowledge there are 1536 pixels to fill in and each pixel can have 1 out of 16777216 possible colors from the hex color palate.

7.46*10^244700  The approximate number of possible chunks naturally generated in the Minecraft world, excluding entities.

Class 3 Numbers
2.63*10^10275621677278468246  The approximate number of unique Minecraft worlds that can be built in creative, (this includes the Nether and the End realms). This number is in between an Attillion and a Zeptillion.
