|  |  D.7.1.7 cyclotomic Procedure from libraryfinvar.lib(see  finvar_lib).
 
Example:Usage:
cyclotomic(i); i integer > 0
Returns:
the i-th cyclotomic polynomial (type <poly>) as one in the first ring
variable
Theory:
x^i-1 is divided by the j-th cyclotomic polynomial where j takes on
the value of proper divisors of i
 |  | LIB "finvar.lib";
ring R=0,(x,y,z),dp;
print(cyclotomic(25));
==> x20+x15+x10+x5+1
