comment Websites that promote co-operation and social networking among mathematicians
@GitGud Again, I read the entire question. This question has nothing to do with Math.SE at all. The downvote is for the mismatch between the first paragraph and the second one.

comment Websites that promote co-operation and social networking among mathematicians
I read the entire question. I downvote it because I think we are no facebook. We are a community. We are a Q&A site. I don't know about others. I come here to learn math, not to socialize.

comment Are NSA Mathematicians second-rate?
Actually, I am hoping NSA mathematicians would read this question and give us answers. They should have a chance to defend themselves.

@user1729 I am incoporating your comment into my answer. I do mean basic level. You don't expect first year undergrad math student becoming an expert in set theory and logician in a year, do you?

comment Maths at university
@user1729 I actually study group theory, too. My reasoning is that you cannot be a good group theorist without knowing set theory. Remember the OP is just starting undergrad math.

comment Routing Automaton
@ArthurFischer I am not sure the routing automata here is different from synchronizable DFA in Exercise 1.59 of Sipser's book. If they are the same, I think this is a homework problem.

comment Routing Automaton
What does it mean by $\to^*$ ? If $M$ is deterministic, there is only one $q'$ such that $\delta (q,w) = q'$. What do you mean by individual?

comment Is there a finite commutative semigroup $S$ with $S^2 = S$ which is not a monoid?
What do you mean by $S^2$ ? $SS$ ? I thought $SS = S$ means the binary operation is closed.
