For questions 11 and 12, matrix A\mathbf{A} describes a binary relation R\mathbf{R} (rows and columns correspond to elements 1 to 6).

A=[100010111111101110000110000010001111]\mathbf{A} = \begin{bmatrix} 1 & 0 & 0 & 0 & 1 & 0 \\ 1 & 1 & 1 & 1 & 1 & 1 \\ 1 & 0 & 1 & 1 & 1 & 0 \\ 0 & 0 & 0 & 1 & 1 & 0 \\ 0 & 0 & 0 & 0 & 1 & 0 \\ 0 & 0 & 1 & 1 & 1 & 1 \end{bmatrix}

Let S\mathbf{S} be the transitive closure of R\mathbf{R} and each element is a set. If S\mathbf{S} reflects operators' behavior on Set, what are possible operators?
