It may not matter. Someone may have made a number far greater than anything that could be produced as a result of mashing together every number on this wiki, tuckered away in a notebook "in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying Beware of the Leopard". Unless you everything in existence, we can't be sure someone hasn't already made a bigger number.

Even now, Sasquatch may not be the largest. There could be a scroll from the 12th century with an even bigger and uniquely obtained number*, who knows?

*Okay probably not from the 12th century, since set theory wasn't really a thing back when, but still.
