## Visualising the Real Orthogonal Group

In the post Can You See in Four Dimensions?, we saw some ways of visualising functions plotted in four-dimensional 'space' in various ways. Of course, we used colour and time for two dimensions because it is a bit difficult to plot in four actual spatial dimensions! Here is another example: the orthogonal group $\mathrm{O}_2(\mathbb{R})$ […]
