$S$ is a set given by $S=\{1,2,3,\dots,4n\}$, where $n$ is a natural number. $S$ is partitioned into $n$ disjoint subsets $A_{1},A_{2},A_{3}\dots,A_{n}$ each containing four elements. It is given that in everyone of these subsets there is one element, ... equal to $2$ $n\neq2$ but can be equal to $1$ It is possible to satisfy the requirement for $n=1$ as well as for $n=2$
