What is the least positive integer n that can be placed in the following expression:
n!(n+1)!(2n+1)! - 1
and yields a number ending with thirty digits of 9's.
If 1^3 + 2^3 + 3^3 = m^2 where m is also an integer. What are the next three consecutive positive integers such that the sum of their individual cubes is equal to a perfect square?
