### Computing homotopy types using crossed n-cubes of groups

#### Abstract:

This paper is a slightly edited version in {\small \LaTeX\ } of the paper of the same title which appeared in the {\em Adams Memorial Symposium on Algebraic Topology}, Vol 1, edited N. Ray and G Walker, Cambridge University Press, 1992, 187-210. It gives a survey of some computational uses in homotopy theory of various structures related to multiple groupoids.
