- List of large cardinal properties
This page is a list of some types of cardinals; it is arranged roughly in order of the consistency strength of the axiom asserting the existence of cardinals with the given property. Existence of a cardinal number κ of a given type implies the existence of cardinals of most of the types listed above that type, and for most listed cardinal descriptions φ of lesser consistency strength, V(κ) satisfies "there are unboundedly many cardinals satisfying φ".
The following table usually arranges cardinals in order of consistency strength, with size of the cardinal used as a tiebreaker. In a few cases (such as strongly compact cardinals) the exact consistency strength is not known and the table uses the current best guess.
* "Small" cardinals: 0, 1, 2, ..., ,..., , ... (see
* weakly and strongly inaccessible, α-inaccessible, and hyper inaccessible cardinals
* weakly and strongly Mahlo, α-Mahlo, and hyper Mahlo cardinals.
* reflecting cardinals
* weakly compact (= Π11-indescribable) Πmn-indescribable , totally indescribable cardinals
* λ-unfoldable, unfoldable cardinals
* almost ineffable, ineffable, "n"-ineffable, totally ineffable cardinals
* α-Erdős cardinals (for
countableα), 0# (not a cardinal), γ-Erdős cardinals (for uncountable γ)
* almost Ramsey, Jónsson, Rowbottom, Ramsey, ineffably Ramsey cardinals
* λ-strong, strong cardinals
* Woodin, weakly hyper-Woodin, Shelah, hyper-Woodin cardinals
superstrong cardinals (=1-superstrong; for "n"-superstrong for "n"≥2 see further down.)
* subcompact, strongly compact (Woodin< strongly compact≤supercompact), supercompact cardinals
* η-extendible, extendible cardinals
* "n"-superstrong ("n"≥2), "n"-almost huge, "n"-super almost huge, "n"-huge,"n"-superhuge cardinals (1-huge=huge, etc.)
rank-into-rank(Axioms I3, I2, I1, and I0)
Reinhardt cardinals (not consistent with the axiom of choice)
* 0=1 is (somewhat jokingly) listed as the ultimate large cardinal axiom by some authors.
