Heatmap

To create this heatmap, we sampled 1,000,000 permutations of length 300 uniformly at random. The color of the point \((i, j)\) represents how many permutations have value \(j\) at index \(i\) (darker = more).

This specification was found using the strategy pack "Point Placements" and has 163 rules.

Found on November 07, 2021.

Finding the specification took 266100 seconds.
