It is known that the procedure called Grade Correspondence Analysis (GCA) transforms any bivariate contingency table into an approximation of table with a very regular positive dependence, called total positivity of order two (TP2). This fact is reminded in Sections 2 and 3, illustrated there by the GCA transformation of an artificial contingency table [T_8x6]. A search for rows and/or columns of table [T_8x6], which most strongly outlie from the TP2 pattern, is described in Section 4. Section 5 presents the outliers found in three large contingency tables, containing the occupational mobility data from Britain and Poland and the parliamentary election data from Poland.
