 OFFSET 2,1 COMMENTS Also where x^(1/x^(1/3)) is a maximum. - Robert G. Wilson v, Oct 22 2014 LINKS Harry J. Smith, Table of n, a(n) for n = 2..20000 Index entries for transcendental numbers FORMULA From Peter Bala, Jan 12 2022: (Start) e^3 = Sum_{n >= 0} 3^n/n!. Faster converging series include e^3 = 18*Sum_{n >= 0} 3^n/(p(n-1)*p(n)*n!), where p(n) = n^2 - 3*n + 5 and e^3 = -162*Sum_{n >= 0} 3^n/(q(n-2)*q(n-1)*n!), where q(n) = n^3 + 8*n - 3. e^3 = 22 - Sum_{n >= 0} 3^(n+4)/((n+3)^2*(n+4)^2*n!) and 22/e^3 = 1 - 2*Sum_{n >= 0} (-3)^(n+2)*n^2/(n+3)!. e^3 = lim_{n -> oo} f(n+2)*f(n)/(n^2*f(n+1)^2), where f(n) = n^(n^2). Compare with e = lim_{n -> oo} g(n+1)/(n*g(n)), where g(n) = n^n. (End) EXAMPLE exp(3) = e^3 = 20.0855369231876677409285296545817178969879... - Harry J.
