      Shi, Minjia; Helleseth, Tor; Özbudak, Ferruh (Journal article; Peer reviewed, 2023)
      Let Fq0 be a finite field of odd characteristic. For an integer s≥1 , let Cs(q0) be the generalized Zetterberg code of length qs0+1 over Fq0 . If s is even, then we prove that the covering radius of Cs(q0) is 3. Put q=qs0 ...
