### Is there a feasible way to passively crosscheck sequences against the OEIS database?

What this questions is not: Can I access OEIS from Mathematica? This topic has been raised more than once and has been well addressed. Here's the situation as it seems to me: OEIS is a tremendously ...

### Find all integer tuples in a bounded region

For given rational numbers $p_1/q_1,p_2/q_2,p_3/q_3$ and a negative integer $d$, I'd like to find quadruples of integers $(w,x,y,z)$ in a rectangle(of particular sidelengths) satisfying the series of ...

### Coefficients of polynomials forming an unimodal sequence

Let $f(x)=\sum_{i=0}^{n}a_{i}x^{i}$ be a polynomial with rational coefficients. I am interested in an efficient way which allows checking whether the finite sequence $A=(a_{i})_{i\in\{0,\ldots,n\}}$ ...

### Accessing internal calculations of Mathematica code

For a given Mathematica program that generates a sequence x of integers, is it possible to also generate equal length sequences of integers that were used internally by the Mathematica kernel to ...
