Definition:Truth Table/Matrix Presentation

Definition
A two-element truth table can be presented in matrix form:


 * $\begin{array}{c|cc}

\implies & T & F \\ \hline T & T & F \\ F & T & T \\ \end{array} \qquad \begin{array}{c|cc} \land & T & F \\ \hline T & T & F \\ F & F & F \\ \end{array} \qquad \begin{array}{c|cc} \lor & T & F \\ \hline T & T & T \\ F & T & F \\ \end{array} \qquad \begin{array}{c|cc} \iff & T & F \\ \hline T & F & T \\ F & T & F \\ \end{array}$

that is, in the form of a Cayley table.

This, however, can be used only when the operation being displayed has two elements.
