In this paper we consider the generalization of Padovan
and Perrin quaternions. We define the split (s, t)-Padovan and (s, t)-
Perrin quaternions which generalize Padovan and Perrin quaternions.
We derive the Binet-like formulas for the split (s, t)-Padovan and
(s, t)-Perrin quaternions. We establish their generating functions.
Also, we obtain certain binomial sums regarding the split (s, t)-
Padovan and (s, t)-Perrin quaternions.
