An n,k,dq code C is l-extendable if C can be extended to an n+l,k,d+lq code. We give some new sufficient conditions for the l-extendability of n,k,d4 codes with d≢0(mod4) using the known results about odd sets in PG(k−1,4). The 3-extendability of quaternary linear codes is investigated through their diversities for the first time.
