Abstract: Let $G_n$ denote either the group $SO(2n+1, F)$, $Sp(2n, F)$, or $G{\mathrm {Spin}}(2n+1, F)$ over a non-archimedean local field of characteristic different from two. We determine all composition factors of degenerate principal series of $G_n$, using methods based on the Aubert involution and known results on irreducible subquotients of the generalized principal series of a particular type.
