## Contents

## Definition

This group is a finite group defined in the following equivalent ways:

- It is the projective special linear group of degree three over field:F9, denoted .
- It is the special linear group of degree three over field:F9, denoted .
- It is the projective general linear group of degree three over field:F9, denoted .

### Equivalence of definitions

The equivalence of definitions follows from isomorphism between linear groups when degree power map is bijective.

## Arithmetic functions

### Basic arithmetic functions

Function | Value | Similar groups | Explanation |
---|---|---|---|

order (number of elements, equivalently, cardinality or size of underlying set) | 42456960 | groups with same order | As : |

exponent of a group | 21840 | groups with same order and exponent of a group | groups with same exponent of a group | |

Frattini length | 1 | groups with same order and Frattini length | groups with same Frattini length | As the group is a simple non-abelian group, its Frattini length must be one. |
