Notation convention for $\{1,\ldots,n\}$
Is there any convention for a notational shorthand for the set $\\{1,\ldots,n\\}$ (defined as $\\{k\in\mathbb{N} \mid k \le n\\}$), where $n\in\mathbb{N}$, that the majority of mathematicians are familiar with?
I find that in some cases in which these sets appear often in the same expression, which can reduce readability, or at least aesthetic cleanness; using some sort of abbreviation would alleviate that.
I don't know how popular this is but I've seen the convention: $$[n]\equiv\\{1,2,3,4,\ldots n\\} $$
