Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Randomizes chunks! Cryptographically proven to bijectively randomize your chunks and generate them in a mostly completely entirely random location, no chunk left behind. Does so to any dimension it can find, really. Was this mod just an excuse to break out the all-time classic, An Introduction to Mathematical Cryptography 2nd Ed, and incorporate finite fields into a Minecraft mod? Absolutely, entirely, yes. Was it overkill and completely unnecessary? Also yes.

This mod is for people who don't believe that hexagons are the bestagons.
