Pen-exitillion

Pen-exitillion, coined by SuperJedi224, is equal to H(165), where H(n) denotes the nth "-illion" number.
It is equal to 103,145,731, and, as such, it is greater than and comparable to bower's Micrillion.
==Etymology==
"Pen" is derived from the prefix "Penta", meaning 5. "Exit" is, in this case, derived from "hexit", or "hexidecimal digit".
