According to the quasi - invariance of the moduli of quadrilaterals under quasiconformal mappings, it is natural to think of approximating the maximal dilatation of the extremal quasiconformal mapping by the ratios of the moduli of quadrilaterals. a key problem is : is it true that the supremum of the ratios of the moduli of quadrilaterals equals the maximal dilatation of the extremal quasiconformal mapping
