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 $PG(2,19).$ %> http://ijmsi.ir/article-1-1360-en.pdf %P 125-133 %& 125 %! %9 Research paper %L A-10-3680-1 %+ Department of Mathematics and Informatics, Technical University of Gabrovo, Bulgaria %G eng %@ 1735-4463 %[ 2022
