New description:
This input in the sage notebook
{{{
R2 = macaulay2.ring('QQ','[x,y]'); R2
}}}
gives this output
{{{
QQ[x..y, Degrees => {2:1}, Heft => {1}, MonomialOrder =>
{MonomialSize => 16}, DegreeRank => 1]
{Lex => 2
}
{Position =>
Up }
}}}
This input in the sage notebook
{{{
I = macaulay2.ideal( ('y^2 -x','x-y') ); I
J = I^3;
print J
print J.gb()
}}}
gives this output
{{{
6 4 2 2 3 4 5 2 2 3 3 2 2
2 3 4 3 2 2 3 2 2 3
ideal (y + 2x*y - 2x y - x , x*y - y - 2x y + 2x*y + x - x y, x
y - 2x*y + y - x + 2x y - x*y , x + 2x y - 2x*y - y )
GroebnerBasis[status: done; S-pairs encountered up to degree 6]
}}}
This may not be limited to the sage notebook. I haven't checked.
