Abstract
Define ( and is the number of prime divisors of . One of the properties of plays a central role: if are prime numbers, with no special condition on other than . This result, combined with the Multiplicity Permutation theorem, will help us establish properties of the next counterexample (say ) to Robin's inequality . The number is superabundant, and must be greater than a number close to one billion. In addition, the ratio has a lower and upper bound. At most multiplicity parameters are greater than . Last but not least, we apply simple methods to sharpen Robin's inequality for various categories of numbers.
