TL;DR: In a previous paper as mentioned in this paper, we showed how a fibration of groupoids gave rise to a six-term exact sequence (three terms of which were groups and three were sets) and that this exact sequence included the bottom end of the topologists' exact sequence of a Fibration of spaces.
Abstract: Introduction In a previous paper ([1]) we showed how a fibration of groupoids gave rise to a six-term exact sequence (three terms of which were groups and three were sets) and that this exact sequence included the bottom end of the topologists' exact sequence of a fibration of spaces, and also in the non-abelian cohomology of a group 0 the six-term exact sequence associated with an exact sequence of coefficient ^-modules
