On nut graphs with two vertex and three edge orbits
Ksenija Rozman, Primož Šparl
Nut graphs are graphs whose adjacency matrix is singular with one-dimensional null space spanned by a vector with no zero entries. In a recent paper, BaÅ¡iÄ, Fowler and Pisanski p…

Self-reverse labelings of distance magic graphs
Petr KováÅ, Ksenija Rozman, Primož Å parl
A graph is distance magic if it admits a bijective labeling of its vertices by integers from up to the order of the graph in such a way that the sum of the labels of all the ne…

Distance magic labelings of Cartesian products of cycles
Ksenija Rozman, Primož Šparl
A graph of order is distance magic if it admits a bijective labeling of its vertices with integers from to such that each vertex has the same sum of the labels of its n…
