# C1523 — Derive the7700 relation from existing legs

## Question

Which already reconstructed quantities determine the cross-manuscript7700 edge?

## Sources

## Results

```json
{
  "LXX_radius": 9030,
  "SP_lower_radius": 1330,
  "difference": 7700,
  "decomposition": [
    9030,
    1330
  ]
}
```

## Finding

7700=9030−1330 follows from the fixed LXX whole inverse radius and SP lower inverse leg. Its placement does not require a new fitted anchor.

## Reassessment

Combine the Babylonian and Covenant partitions of the same12600 interval.
