FORMULA
|
Asymptotically, the best known bounds are (3.6)^n < a(n) <= (6.4 n!)/(n^1/2) for all sufficiently large n. The parameter 3.6 was determined in March 1997 by Thomas Christhof for a random 0/1-polytope of dimension 13, with 254 vertices and at least 17464356 facets. - Jonathan Vos Post, Jul 13 2005
