CrossMatrix[r] gives a matrix whose elements are 1 in a centered cross-shaped region that extends r positions along each index direction, and are 0 otherwise.CrossMatrix[r, ...

PlotRange is an option for graphics functions that specifies what range of coordinates to include in a plot.

PrimeQ[expr] yields True if expr is a prime number, and yields False otherwise.

ScalingMatrix[{s_x, s_y, ...}] gives the matrix corresponding to scaling by a factor s_i along each coordinate axis.ScalingMatrix[s, v] gives the matrix corresponding to ...

Translate[g, {x, y, ...}] represents graphics primitives g translated by the vector {x, y, ...}. Translate[g, {{x_1, y_1, ...}, {x_2, y_2, ...}, ...}] represents multiple ...

Whenever Mathematica draws a three-dimensional object, it always effectively puts a cuboidal box around the object. With the default option setting Boxed->True, Mathematica ...
