Hello Prithwish Sir,
Yes sir that also put me in puzzle. But sir if you want to generate the two set of same lattice with different orientation w.r.t. same reference frame; How is it possible of equal no. of atom in equal space? There is one more thing that is the lattice spacing you are seeing in second case may be w.r.t. the default one. I mean the first one.
Thanking you
