| Abstract: | 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  the group P, and to each 2‐crossed module morphism  the group homomorphism f0 is a fibration. In addition, we study some related properties. |
