Draft:StoneAge Number Scale

The StoneAge Number Scale is a mathematical naming system for extremely large numbers, created by Dutch developer Ivo de Gier in 2026. The system defines one hundred named magnitudes based on prehistoric animals, ordered by estimated body size, in honour of these great animals. Each name is formed by shortening the animal’s name and adding the suffix “Plex”.

The scale is designed as a conceptual extension of large-number naming systems such as the googol, googolplex, and Conway–Guy’s fast-growing hierarchies. The StoneAge Scale introduces a structured, memorable taxonomy for magnitudes far beyond conventional notation.

  1. Structure

Each StoneAge number corresponds to a magnitude defined as: 

   Plexₙ = 10ⁿ × googolplex

where n ranges from 1 to 100. The index n is assigned according to the approximate size ranking of the prehistoric animal associated with the name.

  1. Naming conventions

The naming rules follow four principles: 1. Remove common suffixes such as “-saurus”. 2. Shorten the root to a memorable form. 3. Ensure uniqueness across all 100 entries. 4. Append the suffix “Plex”.

Examples include: - TyraPlex (based on *Tyrannosaurus rex*) - GigaPlex (based on *Giganotosaurus*) - TitanCrocPlex (based on *Deinosuchus*)

  1. Purpose

The StoneAge Scale is intended for: - educational demonstrations of extreme magnitudes - conceptual mathematics - computational experiments - large-number taxonomy research - creative and linguistic applications

  1. Implementation

A full reference implementation is available as an open‑source Python package. The project includes: - a GitHub repository - a public documentation website - a complete list of all 100 Plex numbers - a programmatic API for retrieving names and descriptions

StoneAge Plex Numbers

The StoneAge Number Scale consists of 100 named magnitudes, grouped into Tiers based on relative size. Each Plex number is derived from a prehistoric animal, with the animal name linking to its corresponding Wikipedia article.

StoneAge Plex Numbers

The StoneAge Number Scale consists of 100 named magnitudes derived from prehistoric animals, ordered by estimated body size. Each Plex number corresponds to a magnitude of 10^n × googolplex, where n is the index of the Plex number. The scale is divided into seven Tiers, each representing a major evolutionary or ecological category of prehistoric megafauna.
