A comprehensive review is given on experimental studies of small particles with fivefold symmetry accompanied by an in‐depth theoretical description of their characteristics and computer modeling. The cases of uniform and nonuniform deformations (disclination model), stability and relaxation of elastic stresses in pentagonal particles and needle‐like crystals, models of their formation are discussed.
