A gr
aph is s
aid to be p
ancyclic if it cont
ains cycles of every length from its
girth to its order inclusive;
and
a bip
artite gr
aph is s
aid to be bip
ancyclic if it cont
ains cycles of every even length from its
girth to its order. The p
ancyclicity or the bip
ancyclicity of
a given network is
an import
