I have a submodule of the module Z2[x,y,z]3 given by the 6 generators which are the columns of the matrix
\begin{align} \left(0001+x+y+xy1+y+z+yz1+x+z+xz1+z1+x00y+z001+x1+yx+y0z2\right) \end{align}
How can I implement the sub-module membership test in sage? For example, I want to check whether \begin{align} \left(x+zx+yy+z\right) \end{align}
belongs to the above submodule or not?
