Typo in example 6 in sets-functions-relations/size-of-sets/enumerability.tex

Typo location:

https://github.com/OpenLogicProject/OpenLogic/blob/87ad058e9cbc7e07b855d911cfca1013534a5335/content/sets-functions-relations/size-of-sets/enumerability.tex#L129

What is the typo:

g(n) as defined excludes 1 from the range

Proposed correction:

g(n) = 2n - 1

Good catch, yes. There is an alternate version of this (and two other) sections in this chapter that define enumerability differently, and use \Nat instead of \PosInt. (The definition of g is correct if you are looking for functions Nat -> Nat.) You might like that better for your purposes.
