Query: On Extensions of supersingular representations of ${\rm
  SL}_2(\mathbb{Q}_p)$   In this note for $p>5$ we calculate the dimensions of ${\rm Ext}^1_{{\rm
SL}_2(\mathbb{Q}_p)}(\tau, \sigma)$ for any two irreducible supersingular
representations $\tau$ and $\sigma$ of ${\rm SL}_2(\mathbb{Q}_p)$.
