Brain-Flak, 62 total bytes, 6 unique, 372 points, Cracked

Here is your output:

10993592

There is something special about this number but its not on the OEIS ;)

In case you are thinking of using a computer tool to solve this, you're out of luck, the integer golfer gets 110 bytes for this number:

(((((((((((((((((((((()()()()){}){}){}){({}[()])}{}()()){})){}{}())){}{})){}{}){}){}){}())){}{}){}()){}){}){})

Try it online!

You're going to have to do this one by hand.

Tips

Here are some tips, I will reveal more an more helpful tips over time. Good luck!

10993592 is the 97th term of a sequence on OEIS, but does not appear because only a few terms are included.

My solution uses 3 loops, but they are not nested 3 levels deep.

My solution

((((((()()()){}){}){}){}){}())(({(({})[()])}{}){{({}[()])}{}})

Try it online!

This uses one of my favorite tricks, the code

(({(({})[()])}{}){{({}[()])}{}})

computes the nth term of A090809. The full submission just pads the code with a 97 to make a large number.
