Mepentacontillion

Mepentacontillion is equal to \(10^{3\times 10^{153}+3}\) or \(10^{3\textrm{ quinquagintillion}+3}\) using the short scale definition of quinquagintillion. It is defined by Trakaplex using generalizations from Jonathan Bowers' Tier 2 illion system. It was first mentioned on an answers.com post asking what is bigger than myrillion.Are there numbers bigger than myrillion?
