Under headings such as "In the leisure hours," sometimes there are problems serving one flat expanded shape, for example a hexagon, and the form of her other flat shape, for example square. In this case, the two high-symmetry plane figures are composed of identical asymmetrical elements. At the time, leading craftsman in this kind of expansions and collapses reputed Australian Harry Lindgren (Lindgren G. Interesting challenges to cutting. -M .: Mir, 1977). To further complicate the solution of these problems, put additional condition to do the least possible number of components. Lindgren and other lovers are addicted to expansion figures, even dared to decompose tile patterns. As an illustration of the expansion borrow the pattern of octagons with small squares of squares motif in the same area as octagons, and small squares in the new pattern is stored, but few displaced position.
