    • The stone (1) has an approximately square base with a first pair of opposite sides planar while each side of a second pair includes two partial faces (9, 10) each inclined outwardly from a vertical plane extending through the vertical corner edges (12) of the second side. The two partial faces (9, 10) intersect in the vertical central edge (11) located in the plane of symmetry of the paving stone extending between the opposite second sides. The corner edges (12) of the paving stone extend vertically from the base for a portion of the height of the stone and then are bent angularly (12%) inwardly for the remainder of the height. The upper part of each first side and second side has a pair of triangular gusset-like surfaces (16) inclined from the vertical. The edges (20, 22) of the top face form an octagonally shaped boundary. Due to the above construction adjacent stones in a row have the greatest possible contact along the central edges or partial faces for the transmission force within a row or in a plurality of adjacent rows. The center line (M) of the rows can be rectilinear (Figure 5) or curvilinear (Figure 6).
