%N Decimal expansion of (7+sqrt(33))/4.
%C Decimal expansion of the shape (= length/width = (7+sqrt(33))/4) of the greater (7/2)-contraction rectangle.
%C See A188738 for an introduction to lesser and greater r-contraction rectangles, their shapes, and partitioning these rectangles into a sets of squares in a manner that matches the continued fractions of their shapes.
