@cairdcoinheringaahing https://codegolf.stackexchange.com/questions/230509/find-the-erd%c5%91s-woods-origin I think the wording here might be a bit wrong (or confusing)
`output a positive integer a for which no element of (a,a+1,a+2,...,a+k) is coprime to a or a+k.`
should this not be coprime to a *and* a+k?
