Definition df-tr 4386
Description: Define the transitive class predicate. Not to be confused with a transitive relation (see cotr 5210). Definition of [Enderton] p. 71 extended to arbitrary classes. For alternate definitions, see dftr2 4387 (which is suggestive of the word "transitive"), dftr3 4389, dftr4 4390, dftr5 4388, and (when is a set) unisuc 4795. The term "complete" is used instead of "transitive" in Definition 3 of [Suppes] p. 130. (Contributed by NM, 29-Aug-1993.)
