y is by default interpreted as Wedge[x,y]. Used to mean wedge or exterior product and other generalized antisymmetric products. Occasionally used for generalized notions of intersection. Not the same as \[And], \[CapitalLambda] or \[RawWedge]. See The Mathematica Book: Section 1.10.8, Section 3.10.4. See also: \[Vee], \[UpArrow], \[Intersection], \[SquareIntersection], \[CircleTimes].
