I was able to find a source from The Metropolitan Museum of Art’s website. it seems that it would’ve actually gone up to the 20th letter.
A number of polyhedral dice made in various materials have survived from the Hellenistic and Roman periods, usually from ancient Egypt when known. Several are in the Egyptian or Greek and Roman collections at the Museum. The icosahedron – 20-sided polyhedron – is frequent. Most often each face of the die is inscribed with a number in Greek and/or Latin up to the number of faces on the polyhedron.


I hate the way the media makes this problem so much worse by incorrectly describing LLMs. They can’t “have intelligence”. They are incapable of any kind of thought. The “intelligence” of GPT1 and GPT5 are the same, in that neither have any. They are complex computational algorithms designed to generate text from prompts. That is absolutely not the same thing as thinking or knowing things.
There are entire cults springing out of the ground believing LLMs to literally be thinking feeling beings 💀 we are so beyond fucked.
