The development of nuclear structure physics is driven by the discovery of new phenomena and the need to understand them. One of such challenges is nuclear hyperdeformation (HD); a state of the nucleus characterized by extreme shape elongation in a third minimum of the potential energy surface. Theoretical investigations of HD at high spin were carried out only in the framework of the macroscopic+microscopic method so far. I present a study within cranked relativistic mean field (CRMF) theory, which covers the $Z=40-58$ part of nuclear chart. It is centered around the following questions: (i) what are the best regions for the observation of nuclear HD, (ii) which features of nuclear many-body system favor or prevent the observation of discrete HD bands, (iii) what are the general features of the HD rotational bands, and (iv) which
methods can be used for configuration assignment of the HD bands.
