 [^/P-`mvÇ-ıḃ-ṫ€]*

Python regex.

Tightening the knot, this bans some more useful things, for your aid here are the banned bytes:

*just under a third of them!*

For an input of `4` mine outputs:

 1 2 3 4
 8 7 6 5
 9 10 11 12
 16 15 14 13

...because I formatted a list of lists as a grid with `G`.
