When the cube placed on a large sheet of paper, the wet paint will imprint a colored square on paper. The cube can be flipped over any of four bottom edges, imprinting another color in adjacent square.

Using chess notation, if we place the cube on square d4, is it possible to paint e4 in the same color as d4, flipping the cube as descibed above?

(x + 5)2 + (y - 1)2 = 16

(x + 5)2 + (y - 1)2 = 4

(x - 5)2 = (y + 1)2 = 4

(x - 5)2 + (y + 1)2 = 16
