There are many catalogs in astronomy -- Messier, Caldwell, NGC, IC, Abell, LDN, LBN, VDB, etc. Why so many catalogs???
Well, for one thing there are a LOT of objects out there. I'm talking DOZENS (as in billions of dozens). People keep trying to divide them into various groupings for easier management. Plus its just fun to count things, right? Right!
So this galaxy is called NGC 4236. That means it has the privilege of being object number 4236 in the NGC catalog (where NGC stands for "New General Catalog"). But like the hero Number 6 from my favorite TV show, The Prisoner, surely a galaxy resents being reduced to a mere number.
Some galaxies are more fortunate. If a galaxy is especially shapely, then it transcends its' numerical prison and is given a catchy nickname, like "Whirlpool", or "Sombrero", or "Sunflower". So even though this little galaxy in Draco may not be on anybody's top ten list, I think it deserves better than a mere number. So let's hear it -- what would YOU call it? Until somebody suggests something better, I'm calling it "Cabbage Slice".

Also of note, the little galaxy at the upper left called PGC 40367 (that's right, another catalog).
