The IthMersenne(i) command returns the ith smallest number n such that 2n−1 is known to be prime.
If 2n−1 is prime, then it is said to be a Mersenne prime.
There are currently 51 known Mersenne primes, but the rankings of the forty-fifth to fiftieth Mersenne primes are provisional, since there might be undiscovered Mersenne primes greater than the forty-fourth but less than the fiftieth.
An error will be displayed if i is greater than 51.
Error, (in NumberTheory:-IthMersenne) only 51 Mersenne primes are known
The NumberTheory[IthMersenne] command was introduced in Maple 2016.
