In this article, we define the hyper-dual bicomplex Jacobsthal quaternions. We give some properties of these quaternions. Moreover, we investigate the Binet formula and calculate Vajda’s identity, Catalan’s identity, Cassini’s identity, d’Ocagne’s identity, and generating functions for hyper-dual bicomplex Jacobsthal quaternions.
