93 (ninety-three) is the natural number following 92 and preceding 94.

In mathematics[edit]

93 is:

There are 93 different cyclic Gilbreath permutations on 11 elements,[9] and therefore there are 93 different real periodic points of order 11 on the Mandelbrot set.[10]

In other fields[edit]

Ninety-three is:

In classical Persian finger counting, the number 93 is represented by a closed fist. Because of this, classical Arab and Persian poets around 1 CE referred to someone's lack of generosity by saying that the person's hand made "ninety-three".[13]
