FRatioDistribution[n, m] represents an F-ratio distribution with n numerator and m denominator degrees of freedom.
MatrixPower[m, n] gives the n\[Null]\[Null]^th matrix power of the matrix m. MatrixPower[m, n, v] gives the n\[Null]^th matrix power of the matrix m applied to the vector v.
FactorialPower[x, n] gives the factorial power x (n). FactorialPower[x, n, h] gives the step-h factorial power x (n, h).
BitLength[n] gives the number of binary bits necessary to represent the integer n.
FindSequenceFunction[{a_1, a_2, a_3, ...}] attempts to find a simple function that yields the sequence a_n when given successive integer arguments.FindSequenceFunction[{{n_1, ...
n!! gives the double factorial of n.
UniformGraphDistribution[n, m] represents a uniform graph distribution on n-vertex, m-edge graphs.
DirichletTransform[expr, n, s] gives the Dirichlet transform of expr with respect to n.
n! gives the factorial of n.
NegativeBinomialDistribution[n, p] represents a negative binomial distribution with parameters n and p.
