Collection*
Values*
Please provide at least 10 values, we suggest to provide about 1000 with a limit of 1200.
You can go to the Sage cell below to compute your values
Show example.
object_name => value

    E.g.

    [1,2,3] => 1
    [1,3,2] => 1
    [2,1,3] => 2
    [2,3,1] => 2
Description*
The first line of the description serves as a title for the statistic. See the formating rules below Show example.
Detailed description of the statistic.

    E.g.

    The major index of a permutation.

    The '''major index''' of a permutation $\sigma$ is defined as
    $$\sum_{i \in Des(\sigma)} i$$
    where $Des(\sigma)$ is the set of all indices $i$ such that $\sigma(i) > \sigma(i+1)$.
References
We suggest to provide references whenever possible. Show example.
References to literature describing the statistic, if applicable.
Preferably, references are given by one or multiple identifiers.
Author and title are retrieved automatically, if possible.

Code
We suggest to provide code or pseudocode whenever possible.
If you provide a Python or Sage implementation of your statistic, please use our standardized format
Standardized format to provide Python or Sage code for statistics
# User provided code
def statistic(x):
    # Your code
    return value_at_x
