Sbiis Saibian

Sbiis Saibian (IPA: /sbiz saɪbjən/, born 1983 ) is an American recreational mathematician and "megalo-arithmologist" who is most famous in the googological community for maintaining a 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 the Extensible-E System. 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 December 2014, he has coined over 9,000 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."
