AlgebraicClosure(K) : Fld -> FldAC
Create the algebraic closure A of the field K. Currently K may be Q, a finite field or a rational function field over a finite field or the rational field.
AlgebraicClosure() : -> FldAC
Create the algebraic closure A of the rational field Q.
AssignNamePrefix(A, S) : FldAC, MonStgElt ->
(Procedure.) Given an algebraically closed field A and a string S, reassign the string prefix of the names of A to be S. By default, this prefix is "r". When new variables are introduced by root taking, they are named by this prefix with the number appended (see A.i below).
