Twenty-three is the ninth prime number, the smallest odd prime that is not a twin+prime (a twin prime is a prime number that differs from another prime number by two, like 11 and 13).
Twenty-three is also the fifth+factorial+prime, the third Woodall prime (In number theory, a Woodall number (Wn) is any natural number of the form Wn+=+n+%2A+2%5En+-1) .
It is an Eisenstein+prime (an Eisenstein prime is an Eisenstein
integer that is irreducible) with no+imaginary part
and real part of the form 3n+-+1.
