We consider the class of compact countable subsets of the real numbers
By using an appropriate partition, up to
homeomorphism, of this class we give a detailed proof of a result
shown by Mazurkiewicz and Sierpinski related to the cardinality of
this partition. Furthermore, for any compact subset of
we show the existence of a
“primitive†related to its Cantor-Bendixson derivative.
