Superfactorial
The superfactorial of 
is defined by Pickover (1995) as
The first two values are 1 and 4, but subsequently grow so rapidly that
already has a huge number of digits.Sloane and Plouffe (1995) define the superfactorial by
which is equivalent to the integral values of the G-Function. The first few values are 1, 1,2, 12, 288, 34560, ... (Sloane's A000178).See also Factorial, G-Function, Large Number, Subfactorial
