comment NSolve won't act on very large powers
@Jeff, did you try increasing the setting of WorkingPrecision instead?

comment How dangerous is 'Overflow occurred in computation' message?
…and by sharing your code, we just might be able to propose reformulations that avoid your overflow problems altogether.

Maybe you can use their API with the built-in functionality for APIs?

Have you looked at RevolutionPlot3D[] already?

comment Construct certain univariate functions over bounded interval having given set of moments
This seems more like a math question than a Mathematica question.

comment Find the number of $n$ such that $n!$ is a sum of three squares
Huh, would've thought keeping everything in integers would be faster. Oh well.

comment Find the number of $n$ such that $n!$ is a sum of three squares
It's annoying that BitShiftRight[] is still uncompilable. Otherwise, nice! BTW: I'd use Quotient[m, 2] instead of Floor[m/2].

Huh. If you set WorkingPrecision to anything other than the default value, it works.

BTW, you might also be interested in PolynomialQ[].

Variables[#^2 - # + 7] will work, tho.

comment Getting PlotPoints value from a Plot
@kglr, that's what I told Jason; the only snag in that is that it doesn't account for PlotRangePadding.

comment Why PolarPlot can have negative $r$?
@John, and I gotta say, the analytic geometry books I've seen all mention that $r$ can be negative. OTOH, they're old, and maybe the OP's newfangled books now have restrictions in place.

comment Getting PlotPoints value from a Plot
Yes, I was merely anticipating people who might ask why you didn't just extract PlotRange from the resulting Graphics[] object.

Did you have a look at the FullForm[] of the output of Flatten[(* stuff *)]?

comment Getting PlotPoints value from a Plot
For your perusal: TracePrint[Plot[{Sin[x], Sin[2 x], Sin[3 x]}, {x, 0, 2 π}], (MaxRecursion -> _Integer) | (PlotPoints -> _Integer), TraceInternal -> True]. You can then apply Charting`get2DPlotRange[] to the output afterwards. (N.B. PlotRange[graphics] and Charting`get2DPlotRange[graphics] will have different results in general, depending on the PlotRangePadding setting.)

comment How to generate higher dimensional convex hull?
Consider for instance the 3D convex hull. The points are organized (alright, that may have been the more appropriate word to use) so that there is a polygon corresponding to each facet of the hull. In the 4D case, you have cells; how should the points be grouped in those individual cells? Or will you be satisfied with a routine that returns just the coordinates of the corners?

comment How to generate higher dimensional convex hull?
Let's restrict ourselves to the 4D case, for simplicity. How do you expect the points making up the corners of your convex hull to be arranged?

comment How to construct the RHS of Wick's theorem
@evan, even if it should turn out to not be what the OP wants, can you maybe post it (if needed, as a self-answered question)? That looks interesting in itself.
