Then, the basic definitions and basic features of this new sequence were examined. Finally, addition operation, the Binet formula, and some special types of generalised Tribonacci quaternions are presentedeninfo:eu-repo/semantics/openAccessquaternionshybrid quaternionsgeneralised Tribonacci sequenceArticlehttps://doi.org/10.1093/jigpal/jzaf004001444076400001Q2
