Seems the first constant is wrong

>>> 1/(2 * (1 - math.exp(-2)))

0.5782588213748329

Instead it should be

>>> 1/2 * (1 - math.exp(-2))

0.43233235838169365

Which handily appears in OEIS (a great resource for random constants and sequences) as http://oeis.org/A247847

Michael Lugo (author of the original post that Mark was responding to) here. I had written $1/2 (1-e^{-2})$ in my post, meaning the 0.4323 constant, but with the usual rules of precedence you do in fact get 0.5782; he just propagated my error.

I fixed it on my side also. Thanks to both of you for the correction.
