Symbol

1. Template:Lb Symbol for the cardinality of an infinite set in a iterative hierarchy of power sets, starting with ℵ₀. Usually indexed by an ordinal number.

   $(2)+\mathrm{ð}{\beth }_0={\mathrm{\aleph }}_0$, ${\beth }_{\alpha +1}=2^{{\beth }_{\alpha }},$ and $\lim {\beth }_{\lambda }\to \sup \{{\beth }_{\alpha }:\alpha <\lambda \}$ for a limit ordinal λ.

Usage notes

Unicode has two code points for the Hebrew letter beth. For normal Hebrew text, U+05D1 Template:M should be used. U+2136 should be used for the mathematical symbol in Latin-script text because it will share the left-to-right direction of that text.
