Tav (number)

From Wikipedia, the free encyclopedia

While in the process of discovering higher and higher cardinal numbers, Georg Cantor denoted one by the last Hebrew letter of the alphabet; Tav, Taf or Taw as some people say, was a cardinal.

It is not quite clear what Taw denoted. If Taw had the cardinality of all cardinals, a contradiction would arise, in parallel to the Burali-Forti paradox with the Absolute Infinite, the largest conceivable "number". No notes were given to show that it was either an indescribable cardinal or an inaccessible cardinal.
