Hi,
I want to create the multiplicative group (Z/7Z)*={1,2,3,4,5,6}
I did these steps:
sage:
n=7
sage:
Zn=Zmod(n)
sage: G=Zn.unit_group()
sage: list(G)
[1, f, f^2, f^3, f^4, f^5]
sage:
G.inject_variables()
Defining f
Then I want to create the subgroups H generated by f^2=2 mod 7 which is {1,2
,4}.
I did the following steps:
sage: H =
G.subgroup([f^2])
sage:
list(H)
[1, f, f^2]
sage:
Zn(f)
3
"There seems to be a bug in the subgroup method: H should consist of [1,
f^2, f^4]."
cf:
https://ask.sagemath.org/question/57703/how-can-i-manipulate-a-multiplicative-group-of-zmodn/
Is there a solution for this ? Or I miss something?
