Abstract

We characterize the smallest n with GF (2) [X] /(X^n+1) containing an isomorphic copy of GF(2^m). This characterization shows that the representation of finite fields described in a previous issue of the IEEE Transactions on Computers is not "optimal" as claimed. The representation considered there can often be improved significantly.
