Sbiis Saibian

Sbiis Saibian (IPA: /sbiz saɪbjən/) is an American recreational mathematician and "megalo-arithmologist" who is most famous in the googological community for maintaining a "perpetually incomplete" web book called One to Infinity: A Guide to the Finite (formerly A Finite Journey). In the book, he introduces and describes various googological notations and invents his own, called Hyper-E notation and its extension, Cascading-E notation. The site was first publicly launched on December 9, 2008, four days after Googology Wiki was first created.

Saibian's output is prolific. As of March 2014, he has coined over 3000 number names, the most for any single googologist.

"Sbiis Saibian" is a pseudonym, which he says was "invented by typing random letters on a keyboard."
