In the second type of connective a concatenation of propositional expressions in the form \(e_1 ~ e_2 ~ \ldots ~ e_{k-1} ~ e_k\) indicates all the propositions \(e_1, e_2, \ldots, e_{k-1}, e_k\) are true, in other words, their #LogicalConjunction is true.

In the first type of connective a bracketed list of propositional expressions in the form \(\texttt{(} e_1 \texttt{,} e_2 \texttt{,} \ldots \texttt{,} e_{k-1} \texttt{,} e_k \texttt{)}\) indicates exactly one of the propositions \(e_1, e_2, \ldots, e_{k-1}, e_k\) is false.
