# C646 — Generate the Creation–Enoch rail square

## Question

Can one translation recover all four admitted Creation–Enoch spans?

## Inputs

```json
{
  "upper": [
    4244,
    4237
  ],
  "lower": [
    3264,
    3257
  ]
}
```

## Sources

```json
[

]
```

## Results

```json
{
  "matrix": [
    [
      980,
      987
    ],
    [
      973,
      980
    ]
  ],
  "translation": 980,
  "rail": 7
}
```

## Finding

The four comparisons are one seven-year rail translated by980: corresponding980s and crossed973/987. This reuses the same rail generator as the larger calendar family.

## Reassessment

Ask whether the source’s nested14/140/980 spans share one normalized shape.

## Checks

```json
{
  "whole_matrix": true,
  "entries": true
}
