This is probably not the best way, but this is how I'm doing it.

```
array = []
(0..63).each do |i|
i > 31 ? array[i] = "87" : array[i] = "8.7"
i % 32 > 15 ? array[i] += "3" : array[i] += ".3"
i % 16 > 7 ? array[i] += "7" : array[i] += ".7"
i % 8 > 3 ? array[i] += "9" : array[i] += ".9"
i % 4 > 1 ? array[i] += "2" : array[i] += ".2"
i % 2 > 0 ? array[i] += "8" : array[i] += ".8"
end
array.each{|i| puts i}
```

This comes from the idea that each spot a period can be is a boolean decision, and there are 6 possible spots. As 2^{6} = 64, I looped from 0..63
