Middle-sectioned simplices in a four-dimensional affine space
We present the general geometric description and the Euler – Poincare characteristics of middle-sectioned simplexes in the four-dimensional affine space. We demonstrate the relation between such geometrical objects and four-dimensional analogs of the triangular Serpinski napkin.
