I want to work with a multiplicative group of it. I only found that it is possible to do this with Z modulo n in Sage. But my fields are finite extensions of such a field.
If someone has a way to deal with, please help! mathjainSun, 24 Jun 2018 20:44:16 +0200https://ask.sagemath.org/question/42726/Listing elements of (Z/nZ)*https://ask.sagemath.org/question/35006/listing-elements-of-znz/ I want to find all the elements of (Z/nZ)*. Is there a command for that ?
For example if the user gives input 8, the the output will be
{1,3,5,7}.nebuckandazzerSat, 01 Oct 2016 18:28:42 +0200https://ask.sagemath.org/question/35006/get multiplicative subgroup of Z/nZhttps://ask.sagemath.org/question/10346/get-multiplicative-subgroup-of-znz/Is it possible to get a multiplicative group object of integers modulo n?
For example for n=15 the elements are {1,2,4,7,8,11,13,14}
Of course I can get the elements itself with
> R = Integers(15)
> R.list_of_elements_of_multiplicative_group()
but not as a group.
It is also possible to construct the isomorphic group C2 x C4,
but then the elements are not integers:
> G=AbelianGroup([2,4])
