comment Number of lattice points inside a parallelogram defined by a vector on the “rhombic plane”
I think it might be easier to think about this in terms of a lattice (not the "standard" one) on the standard plane. Also, do you need an exact count or bounds or approximations?

Right on the money! I wish I could upvote this $k$ times for a largeish $k$.

comment Bound on graph domination number when min degree is 7
Actually, if the graph has nice structure, the bound can be improved. Let me know if you are still interested in this.

I am not 100% sure - this might be a bit too theoretical for them.

Permament is a great example of an NP-Hard problem, the Riemann hypothesis (afaik) is not. So I'd suggest you edit the question.

comment Which graphs generate a matroidal independence complex?
Looks like I've dropped the ball on this one. Still, I think I shan't delete as perhaps this can be useful as a "don't try that" post...
