## Abstract The Desargues–Levi graph represents important chemical transformations: (1) isomerization routes for some carbonium ion rearrangements, (2) isomerization of trigonal bipyramidal structures, and (3) some pseudorotations of octahedral complexes. The symmetry properties of this graph have

## Abstract Using a canonical numbering of vertices for the graph corresponding to a particular rearrangement of tetragonal–pyramidal complexes, all 120 permutations defining the symmetry for the rearrangement are derived. An examination of the permutations points to the symmetric group __S__~5~, w

Structures X y 3 X Y \* X Y g of symmetry (22" (of which propane is an example) are examined and the rearrangement due to the internal rotation of the end groups X Y s studied. The isomerization graph is constructed, various forms of which are displayed and the symmetry of which has been determined.
