Composition

FilledSmallSquareComposition[, , , ... ] represents a composition of the functions , , , ... .

FilledSmallSquareComposition allows you to build up compositions of functions which can later be applied to specific arguments.

FilledSmallSquare Example: Composition[a, b, c][x] LongRightArrow.

FilledSmallSquareComposition objects containing Identity or InverseFunction[f] are automatically simplified when possible.

FilledSmallSquareComposition has the attributes Flat and OneIdentity.

FilledSmallSquarea @ b @ c gives a[b[c]].

FilledSmallSquarea // b // c gives c[b[a]].

FilledSmallSquare See The Mathematica Book: Section 2.2.9.
