A kayak paddle graph
is the graph obtained by joining cycle graphs
and
by a path of length
(Gallian 2018). A number of kayak paddle graphs are illustrated
above.
is isomorphic to the 3-barbell
graph.
Kayak paddle graphs are planar, cactus, unit-distance and matchstick graphs. They are also bridged and traceable and have arboricity of 2.
Litersky (2011) proved that kayak paddle graphs are graceful when:

2.
(mod 4) for
