  • Intersection[ , , ... ] gives a sorted list of the elements common to all the .
  • If the are considered as sets, Intersection gives their intersection.
  • Intersection[ , , ... ] can be input in StandardForm and InputForm as ... . The character can be entered as inter or \[Intersection].
  • The must have the same head, but it need not be List.
  • Intersection[ , ... , SameTest-> test ] applies test to each pair of elements in the to determine whether they should be considered the same.
  • Intersection[ a , b ] can be entered in StandardForm and InputForm as ab or a \[Intersection] b.
  • See the Mathematica book: Section 1.8.8.
  • See also: Union, Complement.
