Webto n/2 or B(n,d) is large, for n sufficiently large Plotkin’s bound is at worst off by a factor close to three. Theorem 2 is ultimately a consequence of a recent result in analytic number theory which states that any sufficiently large odd number may be written as the sum of three primes which are all close to each other. The idea is to WebIn a linear code over $\mathbb F_q$, in each coordinate position, either all the codewords have a $0$, or each element of $\mathbb F_q$ appears equally often.
