We know, from a previous chapter (fibrations) that the software `Kenzo` knows how to build the total space of the fibration: $B \\times_\\tau {\\cal G}$, which has the same simplices as $B \\times {\\cal G}$ and the same face operators except the last one, given by:\n",

In the Kenzo program, this object $\\tau$ is implemented as an object of class `simplicial-mrph` and \"degree\" $-1$ while a genuine simplicial morphism has degree 0.
