In 1970’s Goppa discovered algebro-geometric codes, where we need explicit curves with many rational points to construct good codes. Recently we found that the sextics, defined by Wiman in 1895 and by Edge in 1980, attain the Hasse–Weil–Serre bound over some finite fields of order p, p2 or p3, for a prime number p. For some sextics among them, we determined the precise condition on the finite field over which the sextics attain the Hasse–Weil–Serre bound. In addition we update 19 entries of genus 6 and 11 entries of genus 4 in manYPoints. org by computer search on these sextics.
