What is still very difficult - trying to explain one of very interesting crop circles property - very precise symmetry by more than one axis - 2, 3, 4, 5, 6, even more, also exact central symmetry and very accurate mirror reflection.
Nini bado ni vigumu sana - kujaribu kuelezea moja ya kuvutia sana mali zao duru - sahihi sana ulinganifu na zaidi ya moja mhimili - 2, 3, 4, 5, 6, hata zaidi, pia halisi ya kati ulinganifu na uakisi sahihi sana kioo.
