Graphical Maybe this is too […] Recently, I was talking about vectors. At that time, I had to stop and recall how I had been representing vectors.

In this paper a new graphical calculus for operating with isometries of low dimensional spaces is proposed. It generalizes a well-known graphical representation of vectors and translations in an ...
