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 "Requirement Placements Tracked Fusion" and has 46 rules.

Found on April 25, 2021.

Finding the specification took 3073 seconds.
