+This is the Dart port of the original [JavaScript implementation](https://github.com/pballett/map3terms) of a small but ingenious test to show how one might reversibly map roughly each square meter of the globe onto a 3-tuple of words using a simplified symmetric encryption method called [Feistel cipher](https://en.wikipedia.org/wiki/Feistel_cipher).
+
+It seems inspired by the existing proprietary geocoding service [What3Words](https://wiki.openstreetmap.org/wiki/What3words) but uses a completely different method and list of words.

 To do this we needed three things:
 1. A function which maps metre-accurate (latitude, longitude) pairs into three 5-digit integers below 40k.
