* 2000 , Greville G. Corbett, Number , page 30:

These are the three best claims for quadrals'. There are several false trails in the literature, that is, suggestions of other Austronesian languages with ' quadrals , which turn out in fact to have four number values not five.

* 2008 , Martin Haspelmath, Language typology and language universals: an international handbook , volume 1, page 819:

There is a question as to whether there are also languages with quadrals (for reference to four entities). However, having raised the issue of paucals, we shall first continue the analysis of these, and only then return to the question

* 2009 , Michael Cysouw, The Paradigmatic Structure of Person Marking , page 203:

Another point is that, judging from the existing descriptions, true trials are extremely rare and true quadrals do not exist.

(mathematics) A set of points with all the combinatorial properties of a quadric (a quadric being the set of points of PG(n'', ''q ) whose coordinates satisfy a quadradic equation). (en)

If we wished to divide the quadrals into classes, there are obviously several ways in which it could be done, all of them arbitrary. The arbitrariness arises because the points exhibit no natural clustering.

* 1925 , John Hubert Scott, Rhythmic prose

The first instinctive step in revising written matter looks to an effecting of quadrals ; any later revision aims at a perfecting of the rhythma.
