comment Is it ever bad to use \left and \right?
Yes, larger has drawbacks. On your last point, I wasn't trying to imply that it wouldn't be clear or the reader wouldn't understand. I was indicating that the part of my brain that deals with a physical 3D world, distracts the part of my brain that deals with abstract equations. I can read the first faster. Internal conflict or at least multi-tasking slows down my ability to process the second. Not to a snails pace certainly, but "slightly longer" when you're talking about sub-second timing can mean ~1.5 - 3 times longer.

comment Is it ever bad to use \left and \right?
Yes. :-) I take your point that conceptually they are at the same level, but they're not being applied the same. If there's a reason to use parentheses to place them at different levels (as in the example), I find it a mental assist to emphasize the separation of the operations. It also helps me pair-match quickly, when each pair is a different size. And lastly, I find the way the t exponent sticks out of the outer parenthesis unaesthetic. (And the way the inner t hangs out of the bottom of its own parentheses, but that's not worth the effort, so I breathe and move on.)

Your ((a+b)(c+d)) is the first example I've seen where \left( ... \right) didn't chose the sizing I'd want it to. Even in the second example, I prefer it over \biggl( ... \bigr) because they leave the i=1 hanging out, making it look like it's not part of the expression, or like it may "fall away".

@PrzemysławScherwentke But rules are not laws, and they're just made up by someone. I find the first natural and graceful. The second clunky and distracting.

I find the 2nd one to be distracting, and much prefer the first.

Your bullets all say "it", but it's not clear to me whether your pronoun is referencing \left( ... \right( or ( ... ), or something else (singular), since they are plural.

comment What is the TeX/LaTeX symbol for subgroup (not normal subgroup)?
@cfr Different meaning indeed. I see how that would change the connotation of my statement. Although, I disagree with Oxford Dictionary's claim that in North America, use of the word moot has anything to do with uncertainty. It has more to do with meaningless, or absence of a difference. In fact, when I wrote that, the phrase "a distinction without a difference" was in my head.

@cfr Oh? I'm American, so west. When I was rereading the conversation(s) to ensure I understood everything presented, I saw that my original verbiage could be interpreted as emotionally charged, so I was simply looking for a similar word without the emotional connotation.

@JukkaK.Korpela Rereading your comment from an hr ago, I see that you already made the distinction between symbol, character (code), and display. My question was not regarding the first, or third, but the second.

comment What is the TeX/LaTeX symbol for subgroup (not normal subgroup)?
Yes @JukkaK.Korpela, that is my question. The inequality symbols and the subgroup symbols, while visually indistinct, are inherently different. I was wondering if there was a separate code/character in TeX/LaTeX for the separate symbol, or whether people use the same characters. Please forgive my beginners ignorance, but I don't see how this is not what TeX/LaTeX are about.(?)

@JukkaK.Korpela I realize people define different platonic symbols for whatever context they're working in, and independently use various computer characters to represent those symbols, and independently display those characters in various fonts. Saying that the screen is displaying a character instead of a symbol is pointless. My statement was that since there does not seem to be any character specifically for the subgroup symbol, people use the same characters as they use for the inequality symbols.

@JukkaK.Korpela The feedback I'm getting seems to indicate the equivalent of: "There are probably extensions of the standard unicode that would have the symbol you're looking for, or you can make your own extension, but there is no known codepoint in the standard unicode that is specifically for what you're looking for." (I realize that in reality, é in unicode is U+00E9.)
