Editing Variable-star designation (section)

==Naming==
The current naming system is:<ref name=levy/>
* Stars with existing Greek letter Bayer designations are not given new designations.
* Otherwise, start with the letter R and go through Z.
* Continue with RR–RZ, then use SS–SZ, TT–TZ and so on until ZZ.
* After ZZ return to the beginning of the Latin alphabet and use AA–AZ, BB–BZ, CC–CZ, and so on, until reaching QZ, but omitting the letter&nbsp;J in either first or second position.{{efn|
Most of this system was invented in [[Germany]], which was still on [[Fraktur (typeface sub-classification)|Fraktur]] at the time, in which the [[majuscule]]s "I" and "J" can be difficult to distinguish.
}}
* Abandon the Latin letters after all 334&nbsp;combinations of letters and start naming stars with V335, V336, and so on.
The second letter is never nearer the beginning of the [[alphabet]] than the first, e.g., no star can be BA, CA, CB, DA and so on.
