Query: Local Oort groups and the isolated differential data criterion   It is conjectured that if k is an algebraically closed field of
characteristic p > 0, then any branched G-cover of smooth projective k-curves
where the "KGB" obstruction vanishes and where a p-Sylow subgroup of G is
cyclic lifts to characteristic 0. Obus has shown that this conjecture holds
given the existence of certain meromorphic differential forms on P_1^k with
behavior determined by the ramification data of the cover. We give a more
efficient computational procedure to compute these forms than was previously
known. As a consequence, we show that all D_25- and D_27-covers lift to
characteristic zero.
