Abstract
It is shown that a cyclic code
of length
over GF
is the maximum distance separable if and only if either
is a prime, in which case
is equivalent, up to a coordinate permutation, to an extended Reed-Solomon code, or
is a trivial code of dimension
. Hence there exists a nontrivial cyclic extended Reed-Solomon code of length
over GF
if and only if
is a prime.
