A field is represented by a record that contains important information
about this field. The GAP library predefines some field records, for
Rationals (see Rationals). Field constructors construct
others, for example
Field (see Field), and
GaloisField). Of course you may also create such a record by hand.
All field records contain the components
They may also contain the optional components
