This is a list of googolisms in ascending order. This list contains ill-defined large numbers, e.g. large numbers defined by BEAF and BIG FOOT, and large numbers whose well-definedness is not known, e.g. large numbers defined by Taranovsky's ordinal notation and Bashicu matrix number with respect to Bashicu matrix system version 2.3.

This page (the main list) lists the more notable googolisms on each class; click the "More..." link at the end of each section to see more googolisms in that class.

Higher computable level

Since the comparison (or even the well-definedness) of numbers of this level is unknown, the order of entries does not necessarily imply the order of the sizes. Also, several numbers are defined by an OCF, which is uncomputable, and hence the fact that they are listed in this table does not mean that their computability is known.
