# Set and set element naming convention

 0 Can I use the a letter, without a subscript to represent a set, when the elements are represented by the same letter with a subscript? I mean, does the notation below looks ok? asked 17 Feb '16, 08:35 Daniel Oliveira 11●2 accept rate: 0%

 0 I would argue against it, although it is not technically incorrect. There's no fixed convention, but lower case letters for sets look a bit goofy to me. What about using $$T_Z$$ for the set? Does that cause any problems. answered 18 Feb '16, 15:14 Paul Rubin ♦♦ 14.6k●4●12 accept rate: 19%
