This survey is devoted to recently obtained results on finite homogeneousmetric spaces. The main subject of discussion is the classification of regular and semiregular polytopes in Euclidean spacesby whether or not their vertex sets have the normal h

Using the Pontryagin maximum principle for the time-optimal problem in coordinates of the first kind, we find the extremals of an arbitrary left-invariant sub-Finsler metric on the Engel group defined by a distribution of rank 2.

In the short note of 1927, Urysohn constructed the metric space R that is nowhere locally separable. There is no publication with indications that R is a (noncomplete) ℝ-tree that has valency c at each point. The author in 1989, as well as Polterov

We study the Lorentzian manifolds M1, M2, M3, and M4 obtained by small changes of the standard Euclidean metric on ℝ4 with the punctured origin O. The spaces M1 and M4 are closed isotropic space-time models. The manifolds M3 and M4 (respectively, M
