The cell rotation graph D(G) on the strongly connected orientations of a 2-edge-connected plane graph G is deรฟned. It is shown that D(G) is a directed forest and every component is an in-tree with one root; if T is a component of D(G), the reversions of all orientations in T induce a component of D(

## Abstract A graph __G__ = (__V__, __E__) is said to be weakly fourโconnected if __G__ is 4โedgeโconnected and __G__ โ __x__ is 2โedgeโconnected for every __x__ โ __V__. We prove that every weakly fourโconnected Eulerian graph has a 2โconnected Eulerian orientation. This verifies a special case of
Each k-strongly connected orientation of an undirect:7d I.&P A \_an be obtained from any other k-strongly connected orientation by reversing consec aLir :!I 3irected paths or circuits without destroying the k-strong connectivity.
