K = Qp(5, print_mode='digits')
C1=CartesianProduct(ZZ,Integers(4));C1
Cartesian product of Integer Ring, Ring of integers modulo 4
C2=CartesianProduct(C1,Z5);C2
Cartesian product of Cartesian product of Integer Ring, Ring of integers modulo 4, 5-adic Ring with capped relative precision 20
C2.is_ring();
There is something missing in your code since Z5 is never defined. I assume that you meant to insert
sage: Z5 = K.integer_ring()Secondly, if you want help then please ask a clear question! All that I see is a block of incorrect Sage code! But I can guess what you might be wanting to ask, given the title of your posting, which is perhaps to verify that the group of units of Z5 is isomorphic to Z x C4 x Z5. Is that correct?
thank you very much! yes,I want what look like multiplicative group and additive group of Q5
