[Wien] sqrt(3)*sqrt(3)-R30 reconstruction

[Michael Gurnett]

Hello all

After succesfully creating calculating normal supercells, I've now reached
the point where I need to perform calculation on a
Si(111)-sqrt(3)*sqrt(3)-R30 reconstruction. However, as Wien can at this
moment only handle integers in generating supercells, I wonder how I
should proceed in creating this new reconstruction. Any help would be
really appreciated (even an old struct file would help).

best wishes
