Googolmilliplex in zeroes

A googolmilliplex (also spelled googolmilleplex in some sources[1]) is equal to a googol followed by 1,000 plexes.[2] In Hyper-E notation it can be written E100#1001 and as a power tower, 1010...10100 (with 1,001 10's).


The name of this number is based on SI prefix "milli-" and the number "googolplex".
