Octonawazilion is a proposed name for the number in the Namkaran framework, a naming system for extremely large numbers described by Project Namkaran.
According to this proposed definition, an octonawazilion is 1 followed by one billion zeros. The name is part of a series of proposed names for numbers with increasingly large powers of ten.
An octonawazilion is defined in the Namkaran framework as:
Since , both expressions represent the same number.
In decimal notation, an octonawazilion is written as 1 followed by 1,000,000,000 zeros. It has 1,000,000,001 digits in total: one leading digit and one billion zeros.
Exponential notation makes it possible to describe this number without writing out all its digits.
The following table compares an octonawazilion with other numbers.
| Name | Mathematical value | Number of zeros after the initial 1 |
|---|---|---|
| Thousand | 3 | |
| Million | 6 | |
| Billion | 9 | |
| Googol | 100 | |
| Nawazilion | 1,000 | |
| Septenawazilion | 1,000,000 | |
| Octonawazilion | 1,000,000,000 | |
| Googolplex |
An octonawazilion is much larger than a googol, a nawazilion, and a septenawazilion. It is still smaller than a googolplex.
Project Namkaran describes a proposed naming system for numbers represented by very large powers of ten. The framework assigns names to different levels of extremely large numbers.
In the proposed sequence, Octonawazilion follows Septenawazilion and comes before Novanawazilion. Each name represents a different numerical value within the framework.
The Namkaran framework is a proposed naming convention. Octonawazilion is not a standard mathematical term in general use.
Numbers such as are far larger than quantities commonly used in everyday counting. Exponential notation allows such numbers to be described without writing out every digit.
The proposed name provides a short way to refer to this number within the Namkaran framework. The framework also proposes names for numbers with even larger exponents.
