From a mistake made in Stirling's approximation to a ratio of factorials that gives a relatively slow quadratic sequence.
Actually Stirling's ratio limit is: limit_{n-> Infinity} ((n-1)/n)^(n-1/2) = 1/e.
Table of n, a(n) for n=0..55.
a=Table[Floor[n^2*((n-1)/n)^(n-1/2)], {n, 1, 200}]
Sequence in context: A196094 A063915 A183859 * A185170 A211340 A061571
Adjacent sequences: A096225 A096226 A096227 * A096229 A096230 A096231
