proper class

noun

Definitions

  1. A class which is not a set.

    • Thus, what is required is not that all proper classes be the size of the class of all sets, but that every proper class has at least as many members in #92;Omega#95;p as there are sets in #92;Omega#95;2, whatever is in #92;Omega#95;2.
    • Any class is either a set or else a proper class. Every set is a class, but not all classes are sets. Specifically, the proper classes are not sets.
