And
(Built-in Mathematica Symbol) e_1 && e_2 && ... is the logical AND function. It evaluates its arguments in order, giving False immediately if any of them are False, and True if they are all True.
ArcCosh
(Built-in Mathematica Symbol) ArcCosh[z] gives the inverse hyperbolic cosine cosh -1 (z) of the complex number z.
ClosenessCentrality[g] gives a list of closeness centralities for the vertices in the graph g.
Cycles
(Built-in Mathematica Symbol) Cycles[{cyc_1, cyc_2, ...}] represents a permutation with disjoint cycles cyc_i.
DifferentialRoot[lde] represents a function that solves the linear differential equation specified by lde[y, x].
HoldAll
(Built-in Mathematica Symbol) HoldAll is an attribute which specifies that all arguments to a function are to be maintained in an unevaluated form.
Item
(Built-in Mathematica Symbol) Item[expr, options] represents an item within constructs such as Grid, Overlay, and Manipulate that displays with expr as the content, and with the specified options applied ...
