  • Construction of medial ternary self-orthogonal quasigroups 
    Fryz, Iryna; Sokhatsky, Fedir (Республіка Молдова, 2022)
    Algorithms for checking if a medial ternary quasigroup has a set of six triple-wise orthogonal principal parastrophes and a set of six triple-wise strongly orthogonal principal parastrophes are found. It is proved that ...
  • Orthogonality and retract orthogonality of operations 
    Fryz, Iryna (A REPUBLICII MOLDOVA. BULETINUL ACADEMIEI DE S¸TIINT¸ E, 2018)
    In this article, we study the connections between orthogonality and retract orthogonality of operations. We prove that if a tuple of operations is retractly orthogonal, then it is orthogonal. However, the orthogonality ...
