I have a B.Sc in computer science and a B.Sc in mathematics from the Technion.

I am interested mainly in abstract algebra and I hope to start graduate school soon to continue study some advanced topics in this area.

Currently I am going over Abstract Algebra by Dummit and Foote to recall old topics and fill some gaps I have, while working full time as a programmer.

This looks like the definition of convexity not of affinity..

comment For all $X \subseteq \mathbb{N}$ there exist $n \in \mathbb{N}$ with $|X| < n$.
Yes. And for your choice there are infinite number of subsets, given any k there is the subset of all element smaller than k. So there is at least one subset per Natural number and thus infinite number of subsets

comment If $A,B$ are subgroups of the group $G$, then $A\cup B\leq G\Leftrightarrow (A\subseteq B \vee B\subseteq A)$.
I don't get your last point "but that also comes to a contradiction" - Why ? Both $A$ and $B$ have the same identity element and that's fine
