We searched for the 6$$alpha$$-condensed state in $$^{24}$$Mg by measuring the $$^{12}$$C+$$^{12}$$C scattering with the SAKRA Si detector array. By using the invariant-mass method for the detected 3$$alpha$$ particles, the inclusive cross sections for the $$^{12}$$C+$$^{12}$$C $$rightarrow$$ $$^{12}$$C(0$$^{+}_{2}$$) + X and $$^{12}$$C(3$$^{-}_{1}$$) + X reactions were determined. In both the inclusive $$^{12}$$C(0$$^{+}_{2}$$) + X channel and the exclusive $$^{12}$$C(0$$^{+}_{2}$$) + $$^{12}$$C(0$$^{+}_{1}$$) channel, the cross section peaked at E$$_{cm}$$ = 19.4 MeV, which correspond to the excitation energy of E$$_{x}$$ = 33.3 MeV in $$^{24}$$Mg. This 19.4-MeV state is a candidate for the 6$$alpha$$-condensed state
