[personal kdb+] vs overload for sudoku

Hi,

The code below provides some data used by a sudoku solution:
(http://thesweeheng.wordpress.com/2008/11/30/more-sudoku-solvers-in-k-
and-q/)

q)9 vs til 81
0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 2..
0 1 2 3 4 5 6 7 8 0 1 2 3 4 5 6 7 8 0..

I cannot see any reference of ‘vs’ here: https://code.kx.com/trac/wiki/Reference/vs
What does ‘vs’ do in this situation?

Also it looks like it only works with the above parameters (param1=9,
param2=0..80).

q)k)4:!16
'nyi

Is this an overload specifically for solving the 3x3 sudoku?!

Regards,
Petru
