Abstract: Let $ F$ be a totally ramified extension of $ \mathbb{Q}_p$. We consider supersingular representations of $ \mathrm{GL}_2(F)$ whose socles as $ \mathrm{GL}_2(\mathcal{O}_F)$-modules are of a certain form that is expected to appear in the mod $ p$ local Langlands correspondence and establish a condition under which they are irreducible.
