Finite Vertex-colored Ultrahomogeneous Oriented Graphs
Irene Heinrich, Eda Kaja, Pascal Schweitzer
A relational structure R is ultrahomogeneous if every isomorphism of finite induced substructures of R extends to an automorphism of R. We classify the ultrahomogeneous finite bina…

A new infinite family of star normal quotient graphs of twisted wreath type
Eda Kaja, Luke Morgan
We construct the first infinite families of locally arc transitive graphs with the property that the automorphism group has two orbits on vertices and is quasiprimitive on exactly…
