Abstract:
All extended binary perfect $(16,4,2^11)$ codes of rank 14 over the field $\mathbb F_2$ are classified.
It is proved that among all nonequivalent extended binary perfect $(16,4,2^11)$ codes there
are exactly 1719 nonequivalent codes of rank 14 over $\mathbb F_2$. Among these codes there are 844 codes classified by Phelps (Solov?eva–Phelps codes) and 875 other codes obtained by the construction
of Etzion–Vardy and by a new general doubling construction, presented in the paper. Thus,
the only open question in the classification of extended binary perfect $(16,4,2^11)$ codes is that
on such codes of rank 15 over $\mathbb F_2$.
