 Title: Satisfiability thresholds of random $k$-XORSAT-Definition: Random $k$-XORSAT CITE{WikiXORSAT} is a random system of $m=\lfloor\alpha-  n\rfloor$ $k$-variable equations over $\mathbb{F}_2$ in $n$ Boolean variables. For-  $k\geq3$, $\alpha_k$ is the density such that, as $n\to\infty$, satisfiability has-  probability tending to $1$ when $\alpha<\alpha_k$ and to $0$ when $\alpha>\alpha_k$-  CITE{PittelSorkin}.+Definition: Random $k$-XORSAT CITE{WikiXORSAT} is a random system of $k$-variable+  equations over $\mathbb{F}_2$.
