# Interesting Rules

The atlas scores rules by a mix of entropy, activity, density, compression, asymmetry, and repeat period. The score is not a universal quality measure; it is a local way to surface rules that are neither empty nor pure static noise.

The 256 rules form 88 symmetry families when grouped by reflection and black-white complementation.

## Class Counts

| Class | Rules |
| --- | ---: |
| geometric | 98 |
| quiet | 90 |

## Notes

- Quietest rule by activity: rule 4 with activity 0.000.
- Highest entropy rule: rule 7 with entropy 1.000.
- Strongest center-of-mass drift: rule 2 with drift -0.012.
- The top scoring family is canonical rule 30 with 4 members.
- The dashboard keeps all 256 rules visible so these labels can be challenged visually.
