A tridimensional intertwining inside a 'tridimensional epicycloïdal' pseudo-torus [Un entrelacs tridimensionnel à l'intérieur d'un pseudo-tore 'épicycloïdal tridimensionnel'].
This picture is defined as:
PR[x,y,z] = = = PA[PX[x,y,z],PY[x,y,z],PZ[x,y,z]]
using the four following tridimensional fields:
PA[x,y,z] = =
PX[x,y,z] =
PY[x,y,z] =
PZ[x,y,z] =
