comment What is a limit point
@TSJ lmgtfy.com/?q=limit+point I believe in your previous remark you had "accumulation points" in mind, i.e. point that are not isolated.

@TSJ Yes they are, they are limits of constant sequences from $S$...

comment Does $A\times A\cong B\times B$ imply $A\cong B$?
Why isnt' it enough to project onto the first component to get $A\cong B$

Then just take the upper bound in the class of cardinals, which is the smallest cardinal bigger than all elements in your set, the proof still goes through.

comment Find Disconnect Graph with Degree Sequence
disconnected means that your graph is cut into several "potatoes" (at least $2$) with no edge between each other. "Connected component" is the name for "potato". If a potato is of size at least $8$, and the total number of vertices is $11$, this means at most $3$ vertices are left for other potatoes.

comment Linear space and cardinals
Indeed, you need to know that the class of cardinals is totally ordered, which requires axiom of choice. Once you know this, just look at all the cardinals of independent subsets, and take the maximal (it is bounded by the cardinal of the whole vector space so you have an upper bound, the maximal always exists).
