Definition df-tr 4412
Description: Define the transitive class predicate. Not to be confused with a transitive relation (see cotr 5233). Definition of [Enderton] p. 71 extended to arbitrary classes. For alternate definitions, see dftr2 4413 (which is suggestive of the word "transitive"), dftr3 4415, dftr4 4416, dftr5 4414, and (when is a set) unisuc 4816. The term "complete" is used instead of "transitive" in Definition 3 of [Suppes] p. 130. (Contributed by NM, 29-Aug-1993.)
