Abstract
One of the main objectives of this research is to use a new theoretical method to find arcs and Blocking sets. This method includes the deletion of a set of points from some lines under certain conditions explained in a paragraph 2.In this paper we were able to improve the minimum constraint of the (256,16) – arc in the projection plane PG(2,17).Thus , we obtained a new {50,2}-blocking set for size Less than 3q , and according to the theorem (1.3.1),we obtained the linear 257,3,24117    code, theorem( 2.1.1 ) giving some examples on arcs of the Galois field GF(q);q=17."
Highlights
Numerous studies in algebraic geometry have been found in various sources, including obtaining the optimal size of the projection plane by intersecting the tangent in PG(2,q)(Yahya &Salim, 2019,pp.312-333), the applications of algebraic geometry, the coding methods, and obtaining the optimal codes( Kasm,& Hamad,2019,pp.130-139) (Nilsson, Johansson, & Wagner, 2019, pp. 238-258)
Definition(1.2.3):Let M be a set of points in any plane An i-secant is a line meeting M in exactly I points .Define ti as the number of i-secants to a set M. ( Hirschfeld,1979) ." Theorem(1.2.4): Let B be a double blocking set in the projection plane PG (2, q):

Let PG(2, q) be the corresponding projective plane( Hirschfeld,1979) ."
