@Leaky Nun helped golfing this a lot, @Praind Suggested a method to save 1 byte, which I formerly thought of, but forgot to edit, @CotyJohnathanSaxman suggested changing the loop.
Explanation
i=8
- Assigns the value8
to a variable calledi
.exec"..."*17
- Execute that block of code (...
) 17 times.print(...)
- Output the result.' '*abs(i)
- Create a String with a space repeated|i|
times..join('1234567890')
- Interleave the string created above with1234567890
, such that|i|
spaces are inserted between the digits.i-=1
- Decrementi
, and by executing it 17 times, it reaches-8
, which creates te repetitive pattern with the help ofabs()
.

P " Paste it above us
:s/\d/& /g " Put a space after each number
Y " Yank this line
G " Move the end of the buffer
p " Paste the line
{ " Move the beginning of the buffer
