In randomly created structures (be they natural or artificial) very often there exist ordered substructures. In this Hungarian language scientific essay we will present some of such structures in graph theory. E.g. R\'edei's theorem, Ramsey theory, Tur\'an's problem, Hamiltonian cycles in De Bruijn graphs.
