Rotations of a die

add to album

It is not easy to visualize the effect of a rotation on the net of a die, without looking at the die itself. For example, if we compare this image with this other, we should be able to see a rotation of 90° around the line that goes through the centres of opposite faces (numbers 3 and 4).
For this reason, it is difficult to visualize the symmetry of a hypercube by observing its nets.

The image belongs to the sections...:
Images of the exhibition (From the exhibitions of matematita)
Symmetry of the cube (3D geometry)
Nets for polyhedra (3D geometry)
Various matters about hypercube (4D geometry)
