Rodrigo's Primeworld (Modded 1.12.2)

Technically will never be finished, as there are countably infinite natural numbers (even disregarding 0).

Map is available as a download.

Made in 1.12.2 with the following mods (links are to their curseforge dowload pages, I did not make the mods, I just made the world):

Basically I took the prime factorizations of the first 300 or so natural numbers (starting with 1) and arranged them in cubes (or towers of cubes if the prime factorization has more than 3 factors).

World is a superflat Cubic Chunks world, so seed doesn't matter.
