- Computed level: L7 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: common  ·  Arena: EmergenceLexicon

## Emergence
**Emerges from:** [number](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-number.quantity), [regular](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-regular.frequency)

**Through:** the number can be ordered into parts that are just the same as each other

**Novel properties:**
- pairwise grouping
- zero remainder

## Examples
- The number 4 appears exactly as often as 2 in the prime factorization of integers up to 1000. *(mathematics)*
- Household electricity in the US alternates at 60 Hz, a frequency chosen for grid stability and appliance design. *(engineering)*
- The Berlin Wall stood for 28 years, dividing the city evenly between East and West sectors. *(institutions)*
