      "description": "J. Tupper concocted the amazing formula  1/2\u003c|_mod(|_y/(17)_|2^(-17|_x_|-mod(|_y_|,17)),2)_|,   where |_x_| is the floor function and mod(b,m) is the mod function, which, when graphed over 0\u003c=x\u003c=105 and n\u003c=y\u003c=n+16 with   gives the self-referential \"plot\" illustrated above. Tupper's formula can be generalized to other desired outcomes. For example, L. Garron (pers. comm.) has constructed generalizations for n=13 to 29.",
