Comment(by vbraun):
I've changed the printing of Chow cycles to the following:
{{{
sage: X = toric_varieties.Cube_deformation(7)
sage: A = X.Chow_group()
sage: A.degree()
(Z, C7, Z^5 x C2 x C2, Z)
sage: a = sum( A.gen(i) * (i+1) for i in range(0,A.ngens()) ) # an
element of A
sage: a
( 3 | 1 mod 7 | 0 mod 2, 1 mod 2, 4, 5, 6, 7, 8 | 9 )
}}}
I'll upload a new patch when #9972 is finished, as this patch will require
some rediffing.
