My son (Charlie C.) asked about what a number would be called if it had a quadrillion zeros.

He came up with a prefix dind-

So dindquadrillion.

Prefix dind meaning "deco index"

Is this type of number already succintly named? If so, what nomenclature do people use? 2001:8003:ED68:D500:5C75:FE6A:9568:ADDC ( talk) 21:48, 2 September 2023 (UTC) reply

I don't think we have or need common names for such numbers, simply because there aren't that many of anything. For example, to describe the number of atoms in the universe, we only need 80 zeros. Even there, 10⁸⁰ seems a lot easier to understand than obscure wording such as a hundred quinvigintillion. Certes ( talk) 22:56, 2 September 2023 (UTC) reply

Well here it is:

Unmillion Unmilliard Unbillion Untrillion Unquadrillion Unquintillion

Duomillion Duomilliard Duobillion Duotrillion Duoquadrillion Duoquintillion

Tremillion Tremilliard Trebillion Tretrillion Trequadrillion Trequintillion

Quattuormillion Quattuormilliard Quattuorbillion Quattuortrillion Quattuorquadrillion Quattuorquintillion

Quinmillion Quinmilliard Quinbillion Quintrillion Quinquadrillion Quinquintillion

That's all. — Preceding unsigned comment added by 178.88.205.90 ( talk) 20:17, 6 September 2023 (UTC) reply

Hectillion = 10^3,078 Unhectillion = 10^3,081 Duohectillion = 10^3,084 Trehectillion = 10^3,087 Quattuorhectillion = 10^3,090 Quinhectillion = 10^3,093 Sexhectillion = 10^3,096 Septenhectillion = 10^3,099 Octohectillion = 10^3,102 Novemhectillion = 10^3,105 213.211.86.128 ( talk) 10:23, 19 September 2023 (UTC) reply

Thank you, but this article is only for common names used widely in reliable sources. Wikipedia does not publish original research such as inventing new names. Certes ( talk) 12:08, 19 September 2023 (UTC) reply

It's 10^{1,000,000,000,000,000,000} or 10^{1018 — Preceding unsigned comment added by 2.132.8.107 ( talk) 14:01, 25 November 2023 (UTC)} reply

That's not a real number. Black Yoshi ( Yoshi! | Yoshi's Eggs) 22:58, 2 February 2024 (UTC) reply

There is a reversed prime number (emirp) defined by Jens Kruse Andersen from Denmark ( http://primerecords.dk) that has 1089 digits. I don't seem to find a name for it in Wikipedia. 115.64.52.116 ( talk) 07:04, 16 March 2024 (UTC) reply

The table for googol and googolplex has UM as an authority, but it hasn't been mentioned before and has no link. I believe it's supposed to represent the HM reference, but it doesn't say that. 130.226.139.26 ( talk) 07:24, 22 April 2024 (UTC) reply
