In the latest bulk quote file OpenPermID-bulk-quote-20190818_124753.ntriples.gz, and also on the openpermid web-site, the RIC for permid 1-55838834838 is MMIJ.J but it should be MTMJ.J. On 2019-07-16 the RIC in the openpermid data changed from MMIJ.J to the correct RIC MTMJ.J but it recently changed back again to the old, wrong, RIC (and the name changed from "MOMMET ORD SHS" back to "MMI HOLDINGS ORD"). I say the RIC is wrong because the Thomson-Reuters tick history service doesn't recognize it, and neither does the Electron real-time service, while they have no problem with MTMJ.J.
