The relevant numerator of an irregular prime which IS NOT a Mangammal
prime has the form 3^n-2.This can easily be identified, on pari,
by {p(n)=(3^n-2)/p'} where p' stands for irregular prime which is not a Mangammal prime.The required number is the only integer when we print
p(n) for n=1,p'-1.

Further observations to be continued.
