# Plato's 127 stadia across the city equal the Richat's 23.5 km

Adding Plato's rings and central island (27 stadia) to the outer wall 50 stadia beyond on either side gives 127 stadia, about 23.5 km, the diameter of the Richat's main rings.

**Still possible** Answers **1** question0

## Where it stands

**Still possible** One piece of evidence for, two against. It needs two reviews to be accepted.

## What it predicts

- The diameter of the Richat's rings, measured to a defined ring, is close to 127 stadia for any accepted length of the stadion.
- The ring widths stand in Plato's proportions of 3, 3, 2, 2 and 1 stadia around an island of 5.

## What would rule it out

- The match holds only for one chosen ring and one chosen stadion, and the structure's full width differs by a large factor.
- The rings' widths bear no relation to Plato's proportions.
