ComplexInfinity represents a quantity with infinite magnitude, but undetermined complex phase.
Cycles
(Built-in Mathematica Symbol) Cycles[{cyc_1, cyc_2, ...}] represents a permutation with disjoint cycles cyc_i.
EdgeQ
(Built-in Mathematica Symbol) EdgeQ[g, e] yields True if e is an edge in the graph g and False otherwise.
EngineeringForm[expr] prints with all real numbers in expr given in engineering notation. EngineeringForm[expr, n] prints with numbers given to n-digit precision.
Indeterminate is a symbol that represents a numerical quantity whose magnitude cannot be determined.
InputField[] represents a blank editable input field. InputField[x] represents an editable input field that currently contains the expression x. InputField[Dynamic[x]] takes ...
MapIndexed[f, expr] applies f to the elements of expr, giving the part specification of each element as a second argument to f. MapIndexed[f, expr, levelspec] applies f to ...
Map
(Built-in Mathematica Symbol) Map[f, expr] or f /@ expr applies f to each element on the first level in expr. Map[f, expr, levelspec] applies f to parts of expr specified by levelspec.
Max
(Built-in Mathematica Symbol) Max[x_1, x_2, ...] yields the numerically largest of the x_i. Max[{x_1, x_2, ...}, {y_1, ...}, ...] yields the largest element of any of the lists.
NestWhileList[f, expr, test] generates a list of the results of applying f repeatedly, starting with expr, and continuing until applying test to the result no longer yields ...
