I wanted to make a table (for [table of tavern names]) that uses
*d216* type notation. This is when you roll a *d6* three times (or three
diff colours at the same time and declaring one *d6* as high, one as
middle and one as low) and instead of adding them you concatenate the
numbers.[^nomine] This produces 216 unique numbers.

As it's similar to [base6 / senary][senary]. It has numbers that change
the order of magnitude at the 6<sup>th</sup> digit, for example:

* ...
* 165
* 166
* 211
* 212
* ...

Here's a shell one-liner to generate a markdown table for *d216*:

``` bash
printf '| d216 | foo |\n|:----:| --- |\n' ; \
for i in {1..6}{1..6}{1..6} ; do printf '| %4d |     |\n' "$i" ; done
```

The above produces:

``` markdown
| d216 | foo |
|:----:| --- |
|  111 |     |
|  112 |     |
|  113 |     |
|  114 |     |
|  115 |     |
|  116 |     |
|  121 |     |
|  122 |     |
|  123 |     |
...etc
```

A single brace expansion `{1..216}` wont work, as that uses *base10* and
produces numbers that can't be rolled using *d6*s.

    Nomine]'
