FilledSmallSquare Uninterpretable element.

FilledSmallSquare n is used on output to indicate n omitted pieces in an expression obtained from Short or Shallow.

FilledSmallSquare \[LeftSkeleton] indicates the presence of missing information, and so by default generates an error if you try to interpret it.

FilledSmallSquare Not the same as \[LeftGuillemet].

FilledSmallSquare See The Mathematica Book: Section 3.10.5.

FilledSmallSquare See also: \[RightSkeleton] , \[SkeletonIndicator] , \[Ellipsis] , \[ErrorIndicator] .
