## Abstract

We give short and easily verified proofs of primality for the factors of the
Fermat numbers F_{5}, F_{6}, F_{7}
and F_{8}.
## Comments

The main result is a simpler proof of primality of the larger
factor of F_{8} than is given in
[61].
Proofs of primality of the factors of F_{9},
F_{10} and
F_{11}
may be found in [161].
