Özet
In this study, we mainly show that the functor from the category X2Mod of 2-crossed modules of groups to the category Groups of groups assigning to each 2-crossed module {L,M,P,𝜕2,𝜕1} the group P, and to each 2-crossed module morphism (f2,f1,f0) the group homomorphism f0 is a fibration. In addition, we study some related properties.
