Reversed Engineered from Uniqueness (Cop's Thread)

Question

Given the output of the cop's program (o), the byte-count (n) and the number of unique bytes (c) used, come up with a corresponding piece of code that is n bytes long with c unique bytes which matches the cop's output o.

This is the cops thread. Post solutions that are to-be-cracked here.

The robbers thread is located here.

Cops should post solutions like this:

#[Language], `n` Bytes, `c` Unique Bytes (c*n points) [Cracked](Link-To-Crack)

    [Output]

---
    
(Optional spoiler)

Rules

You may not take any input for your program.
The program must use at least 1 byte, but cannot exceed 255 bytes.
The output itself is also limited to 255 bytes.
The program must have consistent output results when executed multiple times.
If your submission is not cracked within 7 days, you may mark it as "safe".
- When marking it safe, post the intended solution and score it as c*n.
- Only mark an answer as "safe" if you really want the +15 for an accepted answer; it's more fun to see how long you can go.

Winning

The uncracked post with the lowest c*n score, wins the cop's thread.
This will be decided after 10 safe answers, or a few weeks.

Caveats

If you feel cocky, you may tell the user the algorithm using a spoiler tag.

@cairdcoinheringaahing. OP has said: "The program must have consistent output results when executed multiple times." — user72349, Nov 10, 2017 at 7:39
Just a suggestion for future CnRs: challenges where the user can choose an arbitrary fixed output are quite problematic for CnRs because people can basically mash their keyboard (barring syntax restrictions) and post the result, because there's no need for the cop to understand what their program is actually doing. Otherwise, this is a neat challenge idea. :) — Martin Ender, Nov 10, 2017 at 8:07
@EriktheOutgolfer As I said "barring syntax restrictions". The point wasn't that you actually post a random stream of characters, but a random valid program which you don't need to understand. And especially in many esolangs, it's very easy to write a program that outputs a decent amount of random garbage without having to understand what that program does. — Martin Ender, Nov 10, 2017 at 9:23
Considering that this challenge has already more than 30 answers, I suggest adding a code snippet which lists uncracked submissions like in this post. — user72349, Nov 13, 2017 at 14:07

JavaScript (ES6), 35 bytes x 16 unique = 560 points - Safe!

Some kind of compromise between a reasonable size and an uncrackable algorithm (as it originally was meant to be ^^).

Expected output (255 bytes):

Alice, 7 bytes, 6 unique, 42 points, safe

-10764@

Try it online!

Solution

gZ/
@o@

Try it online!

g is the easiest way to get a decently big number onto the stack quickly, because it pops two implicit zeros from the stack and then reads the code point at that cell, which is 113 for g itself.

Z then packs 0 and 113 into a single integer, which is a good way to get an even bigger number. That number happens to be -10764.

The number gets printed in Ordinal mode, but then we run into g again in Ordinal mode. The label Alice is looking for is just an empty string. It finds that immediately in the bottom left corner and extracts the @ as a string. When we hit o again, that @ is printed as well.

Afterwards, the IP finds its way to the bottom right corner where the other @ terminates the program.
