The platillion, 1,999-illion or millianongennovemnonagintillion is equal to \(10^{6,000}\), \(1,000^{2,000}\), or 6000-plex.[1] It is equal to 1 millillion in the long scale.

This number can be also called dumillinovemnongentillion in short scale.

Aarex Tiaokhiao gave it the name bimlastillion, referring to the value of this number.[2]
