Construct the Klein
bottle with parametric equations
x = (a+cos(u/2) sin(v) - sin(u/2) sin(2v)) cos(u)
y = (a+cos(u/2) sin(v) - sin(u/2) sin(2v)) sin(u)
z = sin(u/2) sin(v) + cos(u/2) sin(2v)

contains the six circles each of which is inscribed in a face of a cube.
Construct the part of the sphere
x2 + y2 + z2 =1
lying outside the cylinder
(x - 0.5)2 + y2 = 0.25.
