The maximum size of an $(n, r)$-arc in $PG(2, q)$ is denoted by $m_r(2,q)$. In this paper we present a new $(184,12)$-arc in PG$(2,17),$ a new $(244,14)$-arc and a new $(267,15$)-arc in $PG(2,19).$ CP - IRAN IN - Department of Mathematics and Informatics, Technical University of Gabrovo, Bulgaria LG - eng PB - IJMSI PG - 125 PT - Research paper YR - 2022
