Smarandache-Wagstaff Function
Given the sum-of-Factorials function
is the smallest integer for 
Prime such that 
is divisible by . The first fewknown values are 2, 4, 5, 12, 19, 24, 32, 19, 20, 20, 20, 7, 57, 6, ... for 
, 11, 17, 23, 29, 37, 41, 43, 53, 67, 73,79, 97, .... The values for 5, 7, 13, 31, ..., if they are finite, must be very large.See also Factorial, Smarandache Function
