Rotations of a die
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 180° around the line that goes through the midpoints of opposite edges (the edge that joins faces 2 and 3 and the one that joins faces 4 and 5).
For this reason, it is difficult to visualize the symmetry of a hypercube by observing its nets.
