Abstract
The equitable presentation of the quantum superalgebra \({\mathfrak{osp}_q(1|2)}\), in which all generators appear on an equal footing, is exhibited. It is observed that in their equitable presentations, the quantum algebras \({\mathfrak{osp}_q(1|2)}\) and \({\mathfrak{sl}_q(2)}\) are related to one another by the formal transformation \({q\rightarrow -q}\). A q-analog of the Bannai–Ito algebra is shown to arise as the covariance algebra of \({\mathfrak{osp}_q(1|2)}\).
