Given below are the shortest ways to produce a number in the range of 0 to 289 with Deadfish. At most 38 instructions are necessary to reach from 0 to any number in that range.

The shortest way to reach any number is to generate the instructions from right to left by adding `i`/`d`s from the nearest square, add an `s`, then continue isolating recursively until 0 to 3 are reached, which are then generated via `i`s alone. 3 is included since it would otherwise be generated as `iisd` - its nearest square is 4.

For example, the code for 33 generates as such:

```      <code for 33>
<code for 36>ddd nearest square
<code for 6>sddd square root
<code for 4>iisddd nearest square
<code for 2>siisddd square root
iisiisddd ii
```

For numbers above 240, we theorize the same method holds, except for a couple caveats:

• The nearest valid square in the range 241 to 272 is no longer 256. Numbers below would lead to 225 = 15², and numbers above would lead to 289 = 17².
• Any squares involving 256 should be avoided.
• 65537 = 256² + 1 needs to go via 255² rather than 257² - they're the same distance, but the former is itself shorter.
