Decimal expansion of the shape (= length/width = ((9-sqrt(17))/8) of the lesser (9/4)-contraction rectangle.
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.
