Let be a n-dimensional row vectorspace over a finite field For , let be a d- dimensional subspace of . denotes the setof all the spaces which are the subspaces of and not thesubspaces of except . We define the partial order on by ordinaryinclusion resp. reverse inclusion, and then is a poset,denoted by resp. . In this paper we show that both and are finiteatomic lattices. Further, we discuss the geometricity of and , and obtain their characteristic polynomials.
