comment What is $\prod_{k=1}^n (1-x^k)$?
Great, thanks. I don't have Andrews but I will see if it's in Stanley's books, which I have at home.

comment What is $\prod_{k=1}^n (1-x^k)$?
@Qiaochu: Assuming it's hard to evaluate in general, are there special values of $n$ for which it's easy to evaluate?

If it's got a name (e.g., "the Herp-Derp polynomial"), or other stuff that will help me find context for it online.

comment What is the asymptotic behavior of A103213 in OEIS?
@Moron: I see that now, didn't parse the a(n) properly. My apologies.

Another elegant answer!

Oh, this is elegant. I'd considered Stirling but got caught up on something. But I didn't anticipate this.

Nice, my original thought was to use Stirling but I must have made a mistake en route. Thanks.

After plotting, a plausible asymptote seems to be (a constant times) $\exp(2n/3)$. But I am not confident of this.

accepted Does the functional equation $f(1/r) = rf(r)$ have any nontrivial solutions besides $f(r) = 1/\sqrt{r}$?
