In your language of choice, write a program that outputs exactly Hello world!. Each character in your program must be repeated n times - you choose n.

For example, you might choose 2 for n. This means that every character used in your source code must be repeated that many times, or 0.

If I were to choose 3 for n, this program would be valid:

ab(b(b(aa)));;;

Rules:

You cannot use any external resources
No user input can be provided
You must output exactly Hello world!, no more, no less. Newlines are the exception, they are optional.
n must be >= 2, to keep things interesting
It's highly discouraged to use comments to accomplish your goal.

Python 3, n = 3, no comments

dwwppHottedHen =print((("H[e]l1l1o\\ !w!orrilidn!\""[::2][:12])))== 2

Not too hard for a Pythonist to understand. ;) (Hint: try "abcdefghijk"[::2] and see what it results in)

By the way, a HottedHen is a warmed up chicken, if you were wondering. (The dwwpp before it stands for drinking water with purple pancakes, because that's what the hens were doing when I was writing it. Everyone knows that purple pancakes go well with water. Obviously.)

I got tired of putting all the = and , and the like in the code, so I ended dumping them all in a String; not a comment, a string. Every valid character is used for a variable name.

echo -e "H\r--w\"!wccdd!\rHello world!"

This displays exactly Hello world!, and is 39 chars if you omit the trailing newline (bash doesn't seem to need it).

If you need a case-sensitive version, it becomes 42 chars:

Golfscript x4 -- No extra symbols -- Using all possible commands

'HHHeeelWWWrrrd'!!! do do 'Hello world!'

I tried to do one that didn't have any extra symbols beyond what was absolutely necessary (though I could have chosen " instead of ' or ")

As a secondary goal I also wanted to put as few characters as possible into a string as possible, so I used the ! operator as such, and I also squeezed in to do operators.

Uses each character exactly 2 times!

Edit: This code is a bit shorter:

Hel<%= Chr((0<0>we=6&"!")+&H6C+hd)%>o world!

And so is this:

Befunge 98 - 26 bytes

Since I had to duplicate the r anyway, I figured I may as well make the source text read left-to-right rather than typical gnirts Befunge style. There's nothing particularly notable about this; I'm not sure if having code that simply isn't executed counts as a comment, but the six characters Hel w! are just ignored.
