Abstract:
We construct new (n,r)-arcs in PG(2,q) by prescribing a group
of automorphisms and solving the resulting Diophantine linear system
with lattice point enumeration. We can improve the known lower bounds
for q=11,13,16,17,19 and give the first example of a double blocking
set of size n in PG(2,p) with n<3p and p prime.
