CarmichaelLambda[n] gives the Carmichael function \[Lambda](n), defined as the smallest integer m such that k^m \[Congruent] 1 mod n for all k relatively prime to n.
ClippingStyle is an option for plotting functions that specifies the style of what should be drawn when curves or surfaces would extend beyond the plot range.
DivisorSigma[k, n] gives the divisor function \[Sigma]_k (n).
FillingStyle is an option for ListPlot, Plot, Plot3D, and related functions that specifies the default style of filling to be used.
HilbertMatrix[n] gives the n*n Hilbert matrix with elements of the form 1/(i + j - 1).HilbertMatrix[{m, n}] gives the m*n Hilbert matrix.
HITSCentrality[g] gives a list of authority and hub centralities for the vertices in the graph g.
ImageScaled[{x, y}] gives the position of a graphical object in terms of coordinates scaled to run from 0 to 1 across the whole image region in each direction. ...
Min
(Built-in Mathematica Symbol) Min[x_1, x_2, ...] yields the numerically smallest of the x_i. Min[{x_1, x_2, ...}, {y_1, ...}, ...] yields the smallest element of any of the lists.
Tooltip
(Built-in Mathematica Symbol) Tooltip[expr, label] displays label as a tooltip while the mouse pointer is in the area where expr is displayed.
VertexTextureCoordinates is an option for graphics primitives that specifies the texture coordinates to assign to vertices.
