Inputs a simplicial, pure cubical, cubical or pure permutahedral complex K and returns the corresponding regular CW-complex.

Inputs a list L=Y!.boundaries of boundary incidences of a regular CW-complex Y and returns Y.

Inputs a list L=Y!.boundaries of boundary incidences of a regular CW-complex Y together with a list M=Y!.orientation of incidence numbers and returns a regular CW-complex Y. The availability of precomputed incidence numbers saves recalculating them.
