  Snake states and Aharonov-Bohm interferences are examples of
magnetoconductance oscillations that can be observed in a graphene p-n
junction. Even though they have already been reported in suspended and
encapsulated devices including different geometries, a direct comparison
remains challenging as they were observed in separate measurements. Due to the
similar experimental signatures of these effects a consistent assignment is
difficult, leaving us with an incomplete picture. Here we present measurements
on p-n junctions in encapsulated graphene revealing several sets of
magnetoconductance oscillations allowing for their direct comparison. We
analysed them with respect to their charge carrier density, magnetic field,
temperature and bias dependence in order to assign them to either snake states
or Aharonov-Bohm oscillations. Furthermore we were able to consistently assign
the various Aharonov-Bohm interferences to the corresponding area which the
edge states enclose. Surprisingly, we find that snake states and Aharonov-Bohm
interferences can co-exist within a limited parameter range.
