Sbiis Saibian

Sbiis Saibian is a recreational mathematician 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 Hyper-E notation and its extension, Cascading-E notation. The site was first publicly launched on December 9, 2008, only a day after Googology Wiki was first created.
