[Question]
  [
Here’s the picture of the first published picture of the Mandelbrot set.
Use the fewest bytes possible to write a program or function that outputs the following.
![the Mandelbrot set](https://upload.wikimedia.org/wikipedia/commons/d/d7/Mandel.png)
A trailing new line is permitted. Character `*` cannot be replaced by any other character.
[Useful information](https://math.stackexchange.com/a/3510304/305967): Center is \$(-0.75, 0)\$, \$\Delta x = 0.035\$, and \$\Delta y = 1.66\Delta x\$. Iteration count is 250.

Very straightforward implementation, with a little bit of trickery to allow using `times` instead of `upto` in the inner loop.
Unfortunately, loop merging is two bytes longer, although it may help in other languages:
```
-1034.upto(1104){|x|z=0;250.times{z=x%69*0.035-2.0101+x/69/17.21i+z*z};putc x%69>0?z.abs<2?42:32:10}

Uses the constants found by Sisyphus.
Mathematica does have such functions as `MandelbrotSetIterationCount` and `MandelbrotSetMemberQ` (which, with the default 1000 iterations, produces a slightly different image). Unfortunately, `MandelbrotSetIterationCount`'s name is a bit too long, while setting the `MaxIterations` option for `MandelbrotSetMemberQ` makes it even more verbose.

### How it works
```

8W                 % Push 2^8, that is, 256
:                  % Range. Gives [1 2 ... 256]
"                  % For each. This iterates 256 times
  U                %   Square, element-wise
  -1.9751:.035:.4  %   Push range from -1.9751 to 0.4 (actually to 0.37) with step 0.035
  -15:15           %   Push range from -15 to 15 (with step 1)
  !                %   Transpose into a column vector
  17.21j/          %   Divide by 17.21j, element-wise
  +                %   Add with broadcast. Gives the complex grid
  +                %   Add element-wise to result from previous iteration
]                  % End
|                  % Absolute value, element-wise
2<                 % Less than 2? Element-wise
42*                % Multiply by 42 (ASCII code of '*'), element-wise
c                  % Convert to char (char 0 is displayed as space). Implicit display
```
As a curious note, the program uses `:` with three different meanings:
* Unary range function (`:` appplied to `256`)
* Ternary range literal (`-1.9751:.035:.4`)
* Binary range literal (`-15:15`)

Since *05AB1E* does not support complex numbers the computation is done in a more manual way, keeping complex numbers as pairs `[a, b]`:
$$(a+bi)^2 = (a^2-b^2) + 2abi$$
```
D        # duplicate the pair
 n       # square each part: [a^2, b^2]
  Æ      # reduce by subtraction: a^2-b^2
   s     # swap to copy
    P    # take the product: a*b
     ·   # double it: 2*a*b
      ‚  # pair both results: [a^2-b^2, 2*a*b]
```
$$|a+bi|>2 \Leftrightarrow \sqrt{a^2+b^2}>2 \Leftrightarrow a^2 + b^2 > 4$$
```

Bearing in mind that actually calculating the Mandelbrot set in [R](https://www.r-project.org/) costs only [123 bytes](https://codegolf.stackexchange.com/a/204933/95126), including full-colour graphic display, this might not be the golfiest solution... but the text encoding was fun anyway...

I also tried printing the bottom half and reflecting, but this increased the byte count to 78 bytes. I also tried printing the reflection of the image and for the bottom half this reduced the byte count to 75 bytes but for the top half it actually increased it to 81 bytes.
I also tried using manual run length encoding but I couldn't even get it as low as 81 bytes.

Since Python 2.7, the default encoding of a file is now ASCII instead of Latin-1, so you need to prepend the file with `#coding=L1` for the smaller version to run.
