 OFFSET 1,1 COMMENTS Decimal expansion of the shape (= length/width = (Pi-sqrt(-4+Pi^2))/2) of the lesser pi-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.
