Abstract
We analyze two types of permutation orbifolds: (i) \(S_2\)-orbifolds of the universal level $k$ vertex operator algebra $V^k(\frak{sl}_2)$ and of its simple quotient $L_k(\frak{sl}_2)$, and (ii) the $S_3$-orbifold of the level one simple vertex operator algebra $L_1(\frak{sl}_2)$. We determine their structures and discuss related $W$-algebras.
