Single Curio View: (Seek other curios for this number)
The smallest number n, (it is also prime and emirp), such
that the product of first n positive even numbers minus 1
is a prime greater than a googol. Note that the product of
first n even numbers minus 1 is given by the form 2^n*n!-1,
where n is the number of even numbers. May we call the
primes of this form, “almost evenian primes”? [Loungrides]
