Here is a list of my most significant googolisms:
Kaboogol: Defined as 10[10{2}100]100 in Bent Arrow Array Notation. Portmanteau of "kaboom" (referring to its size) and "googol".
n-Kaboogol: Defined as 10[10{n+1}100]100 in Bent Arrow Array Notation, e.g. 4-Kaboogol = 10[10{5}100]100
Kaboogolplex: Defined as 10[10{Kaboogol+1}100]100 in BenAAN (Bent Arrow Array Notation). Also can be called a "kaboogol-kaboogol".
Tying Ten: Not my googolism, but my computation of MiTerSkyArk's googolism, which equates to about 1010^10^10^10^2.311591457149 × 10^16.
What Are They: Another MiTerSkyArk googolism, Sentence(3) in Word Combo Functions, equates to about 105.276089995 × 10^24869
