== Etymology ==
The name gargoogol is the smaller counterpart of gargoogolplex, akin to googol being the predecessor of googolplex. Unlike googolplex, gargoogol is not the originator of gargoogolplex, but the other way around, as gargoogolplex is directly named by Kieran Cockburn, while gargoogol is a systematic name simply coming from combining the gar- prefix with a googol as noted by Alistair Cockburn. 
The name emptol comes from the word "empty", referring to the definition of the number in Ampersand Notation.
