with an additional property that for
each vertex v of G,
there is a vertex w in G
such that
where the sum is taken under
addition modulo m for some positive
integer m. A graph G
which admits an outer mod sum labeling is called an outer mod sum graph. In this
paper, we show that every Path
Cycle
Complete graph
and Wheel
are outer mod sum graphs.
