I was wondering how set theory could be categorized. I've heard that category theory can serve as an alternate foundation for math. But a fundamental symbol in the language is ∈. How is this done with arrows?(adsbygoogle = window.adsbygoogle || []).push({});

I was trying to figure out how arrows might be elements of a set (that isn't not a set of arrows), trying to develop an intuition on this. Here's what I came up with. A sequence is kinda two things (it's really only the second, technically):

1. a list of ELEMENTS

2. an ARROW from N to a set

Hmm...
