Su alcune proprietà del semigruppi finiti
Abstract.
Given a finite semigroup S, the smallest integer n
for which S has the property P can be considered as
a "measure" of how much S deviates from being abelian. This integer in
the case of finite groups of order not higher than 32 has been found,
also using the computer, and is at most 6, a value which is reached
only in the case of the symmetric group on 4 objects.
