Abstract: Let k denote a perfect field of characteristic 5. We show that the versaldeformation ring of an element of order 5 and Hasse conductor 2 as automorphismof a ring of formal power series kt computed by Bertin and Mezard, is infact universal. This provides the first example of a non trivial universaldeformation ring in higher conductor.
