I want to use sage to investigate the action of a group on a
particular "set" which is being permuted. Specifically I want to look
at the orbits of particular objects under the action of the group.
The group I'm looking at is the symmetry group of the square:
G=DihedralGroup(4)
I want to apply t

Sage uses a shell that is different from python's (sage uses IPython),
and keeps a history. So while in python the memor

Yaser, which version of Sage are you using? I'm using 4.6, and I
don't see the behavior you're reporting.

Please see this Function :
def D_f_a(f,G):
ABX_Array = []
for c in G:
for x in G:
b = f(x+c)-f(x)
print("b : ",b)
ABX_Array.append((c,b,x))
return ABX_Array

Looks to me like you haven't explicitly defined a, so it's implicitly
defined as in var('a'). Instead,
sage: f(x) = x
sage: G = GF(4,'a')
sage: a = G.gen()
sage: f(a) - f(a+1)

Hi,
According to this function, Is there any function in sage that
element b {"b = f(x+a) - f(x)} on GF(p^n) (p is prime) must be into
G,
For example :
f(x) = x
G = GF(2^2,'a')
G.list() = {0,1,a,a+1}
then f(a) - f(a+1) = -1 must be one of {0,1,a,a+1}
Thx,
