inverse The Inverse of euler totient functionthe Euler Totient Function

Hi, how

How can we calculate the cardinality for of the inverse of totient Totient function of any positive integer n ? I tried going through the : this paper, but there i I couldn't properly understand the procedure.Also i believe there its shown the actual numbers in the set but is it possible to just get the cardinality with lesser caculations?

Thanks
