is it autistic notation to list the set of integers from 1 to

>>7776986
just do

[eqn]
\bigcup\limits_{i = 1}^{k} \{i\}
[/eqn]

I've seen [n] denote the integers 1 through n in combinatorics

>>7776986
How about [math] {\mathbb{N}_{ \leqslant k}} [/math]

>>7776986
Set-theoretically, [math] n = \{0,1,2,\ldots,n-1\}[/math].

>>7776986
you can use [math] \llbracket 1,n \rrbracket [/math]

if you understand " {1,2,...,k}", then it means the notation is perfectly valid since everyone can understand it without ambiguity.

well shit, thanks /sci/ for the half assed tex support.
it looks something like this
[[ 1,n ]]

I'm honestly surprised something like this isn't common, considering how universal the notation for modular integers is.

It just seems so natural, while the whole {1,2,..,n} thing is just clunky.

Something even easier is standard in set theory. >>7777342. And logicians always begin 0.
