2. Consider the relation p- on natural numbers relating numbers that nave tne same number of prime factors. For example, 2-p=3 and 6-p-10, while 6rp 3 and órpr12 (I use the symbol rpr to denote elements that are not related.) Is -p= reflexive? Is =p= symmetric? Is -p= anti-symmetric? Is -p- transitive? Give reasons!
