| Apr 17, 2014 at 16:40 | comment | added | Lucian | I also wasn't exactly expecting Euler's constant $\gamma$ to be so close to $\dfrac1{\sqrt3}$ either, but hey, that's life: it always takes you by surprise! :-) | |

| Apr 17, 2014 at 14:05 | comment | added | Brendan McKay | The Hermitian property means there are only about $n^2/2$ independent entries, so it would make more sense to write it as $3^{-n^2/2}$ and the constant doesn't look strange any more. One can still ask for a heuristic explanation, of course. | |
