I am trying to plot the Heleman Ferguson's Umbilic Torus with the following parametric formula and had no luck, any tip?
\!\(ParametricPlot3D[{
Sin\ u[7 + Cos \((u\/3 - 2 v)\) + 2 Cos \((u\/3 + v)\)], \
Cos\ u[7 + Cos \((u\/3 - 2 v)\) + 2 Cos \((u\/3 + v)\)], \
Sin \((u\/3 - 2 v)\) + 2 Sin \((u\/3 + v)\)}, \ {u, \(-Pi\), \ Pi},
\ {v, \ \(-Pi\), \ Pi}]\)
