\section{4 Dimensions}  So we came across some new but familiar looking concepts. However in 4 dimensions there should be a quaternary, ternary, binary, unary and 0-ry, object/transform. The quaternary ternary  will be \begin{equation} \begin{vmatrix}   \textbf{i} & \textbf{j} & \textbf{k} & \textbf{l} \\ 
...
Therefore \begin{equation}  Q(r_1,r_2,r_3,r_4)=r_1\cdot(r_2\times T(r_1,r_2,r_3)=r_1\cdot(r_2\times  r_3)+... \end{equation}
