Polygonality

As the number of faces increases, the space-fillers contact more distant neighbours, the polygonalities of the faces of contact decreasing as the order of the neighbours increases.

M. Glouberman (1986), Descartes: The Probable and the Certain, →ISBN, page 213: “Conversely, (b) the condition of polygonality is a part of each of the conditions of triangularity, quadrilaterality, etc., and hence the latter are more than the term which collects them: the collecting term is, in other words, less than the terms it collects.”

The common feature of these and earlier was that the polygonality was regarded as an indication of nonimpact, or even non-explosive origin.
