wff Lim A
 
Syntaxcsuc 4068 Extend class notation to include the successor function.
class suc A
 
Definitiondf-iord 4069* Define the ordinal predicate, which is true for a class that is transitive and whose elements are transitive. Definition of ordinal in [Crosilla], p. "Set-theoretic principles incompatible with intuitionistic logic". (Contributed by Jim Kingdon, 10-Oct-2018.) Use its alias dford3 4070 instead for naming consistency with set.mm. (New usage is discouraged.)
(Ord A ↔ (Tr A x A Tr x))
 
Theoremdford3 4070* Alias for df-iord 4069. Use it instead of df-iord 4069 for naming consistency with set.mm. (Contributed by Jim Kingdon, 10-Oct-2018.)

Definitiondf-on 4071 Define the class of all ordinal numbers. Definition 7.11 of [TakeutiZaring] p. 38. (Contributed by NM, 5-Jun-1994.)
On = {x ∣ Ord x}
 
Definitiondf-ilim 4072 Define the limit ordinal predicate, which is true for an ordinal that has the empty set as an element and is not a successor (i.e. that is the union of itself). Our definition combines the definition of Lim of [BellMachover] p. 471 and Exercise 1 of [TakeutiZaring] p. 42, and then changes A ≠ ∅ to A (which would be equivalent given the law of the excluded middle, but which is not for us). (Contributed by Jim Kingdon, 11-Nov-2018.) Use its alias dflim2 4073 instead for naming consistency with set.mm. (New usage is discouraged.)

(Lim A ↔ (Ord A A A = A))
 
Definitiondf-suc 4074 Define the successor of a class. When applied to an ordinal number, the successor means the same thing as "plus 1". Definition 7.22 of [TakeutiZaring] p. 41, who use "+ 1" to denote this function. Our definition is a generalization to classes. Although it is not conventional to use it with proper classes, it has no effect on a proper class (sucprc 4115). Some authors denote the successor operation with a prime (apostrophe-like) symbol, such as Definition 6 of [Suppes] p. 134 and the definition of successor in [Mendelson] p. 246 (who uses the symbol "Suc" as a predicate to mean "is a successor ordinal"). The definition of successor of [Enderton] p. 68 denotes the operation with a plus-sign superscript. (Contributed by NM, 30-Aug-1993.)
