Let $\zeta^{(n)}(2)$ be the $n$-th derivative of the Riemann zeta function, evaluated at $2$. Numerical experiments seem to suggest that $|\zeta^{(n)}(2)|\sim n!$, in the sense that $|\zeta^{(n)}(2)|/n!\rightarrow 1 $ as $n\rightarrow \infty$. Is this a theorem, or is it just another of those numerical illusions that often happen when experimenting with the zeta function?

2It might help to consider what $f(s) = 1/(s - 1)$ does. – Bladewood Feb 11 '20 at 22:55

I realize there is an oscillation, but I was thinking of the magnitude. I have now edited my post. – Valerio Feb 11 '20 at 23:02

3Stated equivalently the OP wants asymptotics for the series$$\sum_{k=2}^\infty\frac{\ln^n{(k)}}{k^2}$$which appears to be asymptotic to $n!$. – Peter Foreman Feb 11 '20 at 23:35
