### Automorphisms of surfaces in a class of Wehler K3 surfaces with Picard number $4$

Arthur Baragar

#### Abstract

In this paper, we find the group of automorphisms (up to finite index) for K3 surfaces in a class of Wehler K3 surfaces with Picard number $4$. In doing so, we demonstrate a variety of techniques, both general and ad hoc, that can be used to find the group of automorphisms of a K3 surface, particularly those with small Picard number.
