For group valued spins such, as SO(2) and SU(2), we prove that there is long range order in 3 or more dimensions along the NL.</span></span></span></span></span></span></span></span></span></span></span></span></span></span></span></span><br><span><span style="caret-color:#000000"><span style="color:#000000"><span><span style="font-style:normal"><span style="font-variant-caps:normal"><span style="font-weight:normal"><span style="letter-spacing:normal"><span style="orphans:auto"><span style="text-transform:none"><span style="white-space:normal"><span style="widows:auto"><span style="word-spacing:0px"><span style="-webkit-text-size-adjust:auto"><span style="text-decoration:none"><span>The proof relies on work of Abbe, Massoulie, Montanari, Sly and Srivastava on group synchronization.
