Septenawazilion 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 system, a septenawazilion is 1 followed by one million zeros. The name belongs to a series of proposed names for numbers with increasingly large powers of ten.
A septenawazilion is defined in the Namkaran framework as:
Since , both expressions represent the same number.
In decimal notation, it is written as 1 followed by 1,000,000 zeros. It has 1,000,001 digits in total: one leading digit and one million zeros.
Exponential notation makes it possible to describe this number without writing out all its digits.
The following table compares a septenawazilion with other numbers.
| Name | Mathematical value | Number of zeros after the initial 1 |
|---|---|---|
| Thousand | 1,000 | |
| Million | 1,000,000 | |
| Googol | 100 | |
| Nawazilion | 1,000 | |
| Septenawazilion | 1,000,000 | |
| Googolplex |
A septenawazilion is much larger than a googol and a nawazilion. However, it is smaller than a googolplex.
Project Namkaran describes a proposed naming system for numbers with extremely large values. The framework assigns names to numbers represented by large powers of ten.
In the proposed sequence, Septenawazilion follows Nawazilion and comes before Octonawazilion. These names represent different numerical values within the framework.
The Namkaran framework is a proposed naming convention. Septenawazilion is not a standard mathematical term in general use.
Numbers such as are too large to be useful for most everyday counting. They can, however, be described using powers of ten and exponential notation.
The proposed name provides a short way to refer to this particular number within the Namkaran framework. The framework also explores names for other numbers with much larger exponents.
