Finding a lower bound in terms of given integers
@FedorPetrov This is known as Liouville's bound. It has been improved: noneffectively, there is Roth's theorem, whereas effectively there is work of Baker and later Feld'man. However, for algebaic numbers of this special form one is likely to do better than BakerFeldman using Pade's approximations (for example, there is work of Bombieri on approximations to $\sqrt[k]{n}$). However, I do not know what the state of the art in these questions is.

Finding a lower bound in terms of given integers
It could be zero. If it is not zero, then giving a lower bound is a difficult diophantine approximation problem because even the rational approximations to $\sqrt[k]{n}$ are difficult (which is the case $\sqrt[k]{p^k n}+0\sqrt[k]{q^k}$). I am no expert however, and do not know the status of these problems.

I downvoted because I think the offtopic questions should not be answered, but closed.

From polynomial ideal over $\mathbb{Q}$ to polynomial ideal over $\mathbb{Z}$
Aha, the trick is not to work with large $D$ as suggested in my question, but with "symbolically large" D, which is what saturation does. Today I learned why saturation is nice!

A specific class of $(0,1)$matrices
Interesting question. I currently doubt that this pattern will persist for larger $n$, but have no proof.

A specific class of $(0,1)$matrices
What does the second paragraph mean: you have a proof that, for $n$ even, most matrices in $T_n$ have even number of $1$'s, or you mean that you computed up to some $n$, and observed this to be this case. In the latter case, how large was your $n$? In the former case, is your question "is this already known"?

Minimum number of people such that 2 can be expected to sit next to each other
@DominicvanderZypen While I am sympathetic to your plea for assistance, MO is not a place to seek assistance with undergraduatelevel material. Not receiving a satisfactory answer on stats.stackexchange.com does not make your question on topic here. Similarly, I should not answer your question as doing so would reward posting offtopic questions.

@DominicvanderZypen This is a very basic probability question (undergraduate level). As an experienced user, you know that if someone here asked "What is 2+2?", they would be downvoted and redirected to resources outside MO. Similarly, your question does not belong to this forum, but it would be ontopic at MSE.
