== Abstract ==&lt;br /&gt;
A Petrie polygon is a closed series of edges on a polyhedron (see Coxeter1 for a more detailed treatment). It is&lt;br /&gt;
generally taken to mean an equatorial polygon (usually skew), for example the regular dodecahedron has six&lt;br /&gt;
skew decagons with vertices that alternate across the equatorial planes parallel to its faces.&lt;br /&gt;
&lt;br /&gt;
A sequence of regular frameworks can be generated by moving the vertices of Petrie polygons anywhere&lt;br /&gt;
between the equatorial planes and the ends of the axes perpendicular to the planes. The sequence passes&lt;br /&gt;
through a position where the skew polygons define the edges of the original polyhedron, and the convex hull of&lt;br /&gt;
the framework corresponds to the polyhedron .. The full sequence defines a series of polyhedra (which are&lt;br /&gt;
isogonal if the original polyhedron is regular). Other isogonal polyhedra can be generated. (or example&lt;br /&gt;
compounds of the antiprisms defined by each skew polygon.&lt;br /&gt;
&lt;br /&gt;
The vertices of moving frameworks generated from Platonic polyhedra define a conjugate framework which&lt;br /&gt;
passes through an identical sequence. and also other frameworks that match the sequences generated by the&lt;br /&gt;
dual Platonic polyhedron.&lt;br /&gt;
