ⓘ Ineffable cardinal

In the mathematics of transfinite numbers, an ineffable cardinal is a certain kind of large cardinal number, introduced by Jensen & Kunen.

A cardinal number κ {\displaystyle \kappa } is called almost ineffable if for every f: κ → P κ {\displaystyle f:\kappa \to {\mathcal {P}}\kappa} where P κ {\displaystyle {\mathcal {P}}\kappa} is the powerset of κ {\displaystyle \kappa }) with the property that f δ {\displaystyle f\delta} is a subset of δ {\displaystyle \delta } for all ordinals δ < κ {\displaystyle \delta
