I ended up translating the Python 3.8 code (the more readable version) [https://codegolf.stackexchange.com/questions/230509/find-the-erd%C5%91s-woods-origin here], 6th post down, and found the first 20 E-W numbers in around 93 seconds. Much slower than Python which has arbitrary precision numerics built-in nowadays but acceptable for Wren.

import "./fmt" for Conv, Fmt

import "./sort" for Sort

k = k + 1

Takes about 15.4 seconds which is significantly faster than Wren-cli, but still nowhere near as fast as the Python version - a majestic 1.2 seconds!
