 OFFSET 1,2 COMMENTS Decimal expansion of shape of a (4/5)-extension rectangle; see A188640 for definitions of shape and r-extension rectangle.  Briefly, shape=length/width, and an r-extension rectangle is composed of two rectangles of shape 1/r when r<1. The continued fractions of the constant are 1, 2, 10, 2, 1, 1, 2, 10, 2, 1, 1, 2, 10, 2, 1, 1, 2, 10, 2, 1, 1, 2... LINKS G. C.
