Order of Structure

$\order {\struct {S, \circ} }$

The order of an algebraic structure $\struct {S, \circ}$ is the cardinality of its underlying set, and is denoted $\order S$.

Thus, for a finite set $S$, the order of $\struct {S, \circ}$ is the number of elements in $S$.

The $\LaTeX$ code for \(\order {\struct {S, \circ} }\) is \order {\struct {S, \circ} } .
