BCH codes use special values of n and k:
n, the codeword length, is an integer of the form 2m-1 for some integer m > 2.
k, the message length, is a positive integer less than n. However, only some positive integers less than n are valid choices for k. See the bchenc reference page for a list of some valid values of k corresponding to values of n up to 511.
