The building block with four vertical planes of symmetry formed by one more basic modules - M(aM*aM*bM) has, in the basic module - M(aM*aM*bM), at least one pair of opposite walls (X, X') the shape of which is symmetrical according to each plane in which a diagonal of the wall and the centre of the building block (Y) lie, the shape of the pair of opposite walls of the building block is identical and designed so as to form joggles (1, 1'). The joggles (1, 1') has circular and/or 4+n-polygonal shape. The building block is formed by one or more modules put next to each other, above each other and/or they are mutually firmly linked by a space construction (2). |
