# Googo-

**Googo-** is a prefix used in a system invented by Andre Joyce to create number names.^{[1]} It was invented to give a retroactive meaning to googol (in this system, googo-l = \(100^{50} = 10^{100}\)).

## Usage Edit

The basic concept of the googo- prefix:

- Convert a number
*n*to Roman numerals. - Take those numerals and apply the googo- prefix.
- The result is \((2n)^{n}\).

For example, a *googocci* is a *googo-* followed by *cci*. *cci* is 201, so a googocci is \((201 \cdot 2)^{201} = 402^{201}\).

## Pronounceability Edit

Improper Roman numerals, such as *ic* = 99 or *vim* = 994, are allowed for pronounceability's sake. The following substitutions are also allowed:

*ij*for*ii**ox*or*iji*for*iii**em*or*ump*for*m**ex*for*x**el*for*l*

## Repdigits Edit

If you need to use a Roman numeral for a number such as 3333333 or 888, you can use a Latin prefix followed by the Roman numeral for the repeated digit. So a *googoquadrix *\(= (quadrix \cdot 2)^{quadrix} = (4\ 9's \cdot 2)^{4\ 9's} = 19998^{9999}\).

## Bars Edit

In Roman numerals, a bar placed over a numeral (except I) multiplies it by 1000 (e.g. \(\overline{V} = 5000\)). The equivalent in Joyce's system is the "-bar" suffix. So *googovbar* \(= 10,000^{5000}\) and *googoumpbar* \(= 2,000,000^{1,000,000}\).

Multiple bars are allowed, producing so-called "barbarian numbers." A sequence of bars can be shortened using a Latin prefix: "barbarbarbar" is the same as "quadrabar."

## Alternative vowels and G-counts Edit

The googo- prefix can be extrapolated to prefixes with different vowels and different numbers of G's. Using Ackermann's Generalized Exponential Notation:

- g-
*n*-g[g]-*m*-*r*\(= g(n,r,g(m,r,g))\)

Where:

*n*and*m*are integers ranging from 1 to 8. When placed in the word, they are transformed by the following key: o = 1, oo = 2, ee = 3, or = 4, ie = 5, i = 6, e = 7, and ei = 8.*r*is a Roman numeral as described above.*g*is the number of G's in the prefix. This can be either two or three, depending on whether an extra G (indicated by brackets) is included.
