The set of thirteen such duals is historically designated the Catalan solids. Perhaps the most striking feature of a Catalan solid is that it is composed of just one kind of face that is not a regular polygon. A face of a Catalan solid can be simply constructed by the Dorman-Luke construction [3, 4, 6, 16], which is based on a dualization process known as polar reciprocation [6], with respect to the midsphere.
In the nineteenth century fustian cutting was a major occupation right across the North West and thousands of people in the cotton towns were employed at it. Sometimes the work was done at tables but more often than not the cloth was stretched across rollers and they'd walk up and down all day, slicing through the threads of the weave row by row, using tiny blades fashioned from watch springs and honed until they were as sharp as razorblades. Cutting even a basic fustian, they could walk ten or eleven miles over the length of a shift. With more sophisticated fustians – fabrics like velveteen, for instance – you had to walk further, much further.
[Rural solar plant] schemes are of little help to industry or other heavy users of electricity. Nor is solar power yet as cheap as the grid.
