Complement[e_all, e_1, e_2, ...] gives the elements in e_all which are not in any of the e_i.

GraphComplement[g] gives the graph complement of the graph g.

GraphDifference[g_1, g_2] gives the graph difference of the graphs g_1 and g_2.

BitNot[n] gives the bitwise NOT of the integer n.

Mathematica usually keeps the elements of a list in exactly the order you originally entered them. If you want to treat a Mathematica list like a mathematical set, however, ...

! expr is the logical NOT function. It gives False if expr is True, and True if it is False.

Integrated into the Mathematica system are powerful functions for analyzing large volumes of discrete and integer data—often conveniently specified using Mathematica's ...

Ordinary mathematical functions in Mathematica are always "listable", so that they are immediately applied in parallel across lists. Mathematica provides a wide variety of ...

Mathematica encapsulates in a small number of functions vast flexibility in rearranging lists with any structure and any number of elements.

Mathematica has been used to make many important discoveries in discrete mathematics over the past two decades. Its integration of highly efficient and often original ...
