Abstract

We study the number of normal measures on a tall cardinal. Our main results are that:

  • The least tall cardinal may coincide with the least measurable cardinal and carry as many normal measures as desired.

  • The least measurable limit of tall cardinals may carry as many normal measures as desired.
