Definition
An arithmetic function on groups is a function that takes in a group and returns a number.
Examples
A simple example of an arithmetic function on groups is the order of a group, taking in a group and returning its order. An example of its value is symmetric group:S3 gets mapped to 6.
Another example of an arithmetic function on groups is the number of subgroups of a group. An example of its value is symmetric group:S3 gets mapped to 6.
An example of an arithmetic function on a certain restricted class groups is the nilpotency class of a nilpotent group. An example of its value is that is is equal to 1 on all non-trivial abelian groups.
