Googology

Googology is the study and nomenclature of large numbers, particularly those related to the googol. Googology, coined by Andre Joyce, is a portmanteau of googol and the "-logy" prefix.

Googology is not to be confused with googlology, the study of the Google search engine.

One who studies and invents large numbers and large number names is known as a googologist, and a large number name is known as a googologism.
