"So, you know Kalle's Ninth Proof of Folding?"
"Yes, I couldn’t have solved Abraxas without it.
Hari Seldon and Gaal Dornick[src]

The Abraxas Conjecture is a mathematic proof that was unsolved for over five hundred years.[1] It was considered to be the last great unsolvable mathematical proof in the galaxy by 12,067 Era Imperial.[2] Dr. Hari Seldon set a competition to solve Abraxas to find another mathematical genius who could understand his work on Psychohistory. Gaal Dornick, from the planet Synnax, solved Abraxas using Kalle's Ninth Proof of Folding.[1]
