JacobiSymbol[n, m] gives the Jacobi symbol (n/m).
MemberQ
(Built-in Mathematica Symbol) MemberQ[list, form] returns True if an element of list matches form, and False otherwise. MemberQ[list, form, levelspec] tests all parts of list specified by levelspec.
NumberFieldRegulator[a] gives the regulator of the field \[DoubleStruckCapitalQ][a] generated by the algebraic number a.
BernoulliB[n] gives the Bernoulli number B_n. BernoulliB[n, x] gives the Bernoulli polynomial B_n (x).
Binomial[n, m] gives the binomial coefficient ( { {n}, {m} } ).
Part
(Built-in Mathematica Symbol) expr[[i]] or Part[expr, i] gives the i\[Null]^th part of expr. expr[[-i]] counts from the end. expr[[i, j, ...]] or Part[expr, i, j, ...] is equivalent to expr[[i]][[j]] .... ...
Abs
(Built-in Mathematica Symbol) Abs[z] gives the absolute value of the real or complex number z.
DependentVariables is an option which specifies the list of all objects that should be considered as dependent variables in equations that have been supplied.
Det
(Built-in Mathematica Symbol) Det[m] gives the determinant of the square matrix m.
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 ...
