Mahlo cardinal

A cardinal number κ > ‭א‬₀ is called Mahlo iff the set U = {λ < κ: λ is inaccessible} is stationary[?] in κ. Assuming that ZFC is consistent, the existence of Mahlo cardinals provably cannot be proved in ZFC.

Mahlo cardinals were first described in 1911 by mathematician Paul Mahlo[?].
