We introduce a technical property (P) and use it to show that every M 3 -space with (P) is an M 1space whose every closed subset has a closure-preserving open neighborhood base. We show that every k-M 3 -space has property (P) and is, therefore, an M 1 -space.

## Abstract Let __P__~1~(__n__), __P__~2~(__n__), __P__~3~(__n__) denote the norm‐polyhedra cube, crosspolytope and sphere in the Euclidean __n__‐space. We consider the polyhedra __D__~__i,j__~(__n__):=__P__~__i__~(__n__)∩__P__~__j__~(__n__) with 1 ≦ __i__ β‰  __j__ ≦ 3. In [2] posed the question abo
