GaussianRationals
is the field of Gaussian rationals, as a set of cyclotomic numbers, see Chapter 18 for basic operations. This field can also be obtained as CF(4)
(see CyclotomicField
(60.1-1)).
The filter IsGaussianRationals
returns true
for the GAP object GaussianRationals
, and false
for all other GAP objects.
(For details about the field of rationals, see Chapter Rationals
(17.1-1).)
