It is proved that if G is a k-connected graph which does not contain K - 4 , then G has an edge e or a triangle T such that the graph obtained from G by connecting e or by contracting T is still k-connected. By using this theorem, we prove some theorems which are generalizations of earlier work. In

We present a reduction theorem for the class of all finite 3-connected graphs which does not make use of the traditional contraction of certain connected subgraphs. ## 1998 Academic Press Contractible edges play an important role in the theory of 3-connected graphs. Besides the famous wheel theore
## Abstract For a graph __G__ we define a graph __T__(__G__) whose vertices are the triangles in __G__ and two vertices of __T__(__G__) are adjacent if their corresponding triangles in __G__ share an edge. Kawarabayashi showed that if __G__ is a __k__βconnected graph and __T__(__G__) contains no ed
We show that if G is a 3-connected graph of order at least seven, then every longest path between distinct vertices in G contains at least two contractible edges. An immediate corollary is that longest cycles in such graphs contain at least three contractible edges. We consider only finite undirect
In [15] , Thomassen proved that any triangle-free k-connected graph has a contractible edge. Starting with this result, there are several results concerning the existence of contractible elements in k-connected graphs which do not contain specified subgraphs. These results extend
