NGC 6901 = IC 5000. Seen only once by Marth, his position, correctly copied into the NGC, is off. This misled Bigourdan to measure a nearby star which he took to be N6901, and to rediscover Marth's galaxy. Thus, it got a second number, IC 5000 (which see). There is only one galaxy in the area, however, and Marth's and Bigourdan's descriptions are near enough that they undoubtedly refer to the same object.
My supposition in RC2 that the galaxy is also = IC 1316 is, however, incorrect. IC 1316 (which see) was another of Bigourdan's discoveries, which he "observed" twice in different places on the same nights on which he also saw N6901. It is, in fact, non-existent.
The RNGC (Sulentic and Tifft 1973) notes that this is a 15.0 mag galaxy. Their coded description reads NF S.
