A homotopy 2-groupoid from a fibration

K.H. Kamps and T. Porter

In this paper we give an elementary derivation of a 2--groupoid from a fibration. This extends a previous result for pointed fibrations due to Loday. Discussion is included as to the translation between 2--groupoids and cat$^1$--groupoids.
