A ( k ,n; f ) – arcs of type (n-7, n) in PG( 2, 7 )


In this paper we study a (k,n;f )-arcs of type ( n-7,n ) in the projective plane PG(2,7) , we construct a (26,11;f )- arc of type (4,11) when the points of weight 0 form an (31,6)-arc of type (3,30,20,0,0,0,4), and the points of weight 2 form an (6,3)-arc of type (4,3,30,20) .For this purpose we use the technique in reference [Barlotti, A.,1977] .
