One-sided isotopes and homotopes of right-alternative algebras

It is proved that every $c$-homotope preserves identical equations for the four-dimensional Mikheev algebra. Moreover, all isomorphisms for the four-dimensional Mikheev algebra and its $c$-isotope are described. It is proved that every central $c$-isotope of the Hentzel algebra is isomorphic to the Hentzel algebra. One-sided isotopic pairs are described.
