Is there a special symbol for the set: $$ \{1, 2, 3, \dots, n\}$$, or $$\{x| 1\leq x\leq n, n \in \mathbb{Z} \} $$?

These are the usual notations (the second is borrowed from computer science): enter image description here

Some people use $$\mathbb{N}_k = \{1, 2, \ldots, k\}$$

Consider that for positive reals the standard symbol, as Wikipedia says, is $\mathbb{R}_{>0}$

Then I think that you can use the following symbol for $\{1,2,...,n\}$ $$\mathbb{N}_{\le n}$$
