A person had a plantation of 22 trees, planted as shown in the diagram:

\[
\begin{array}{llll} 
& \varphi & \varphi & \\
\varphi & \varphi & \varphi & \varphi \\
\varphi & \varphi & \varphi & \varphi \\
\varphi & \varphi & \varphi & \varphi \\
\varphi & \varphi & \varphi & \varphi \\
\varphi & \varphi & \varphi & \varphi 
\end{array}
\]

How should he transplant 6 of them to form 20 rows with 4 trees in each row?
