 If you actually want to check for the presence of an element, use the
-L<(cont)|/routine/(elem), infix ∈> operator for single elements, and the
+L<(cont)|/routine/(cont), infix ∋> operator for single elements, and the
 L<<superset|/language/operators#infix_(>=),_infix_⊇>> and L<<strict superset|/language/operators#infix_(>),_infix_⊃>>
 operators for multiple elements.
