Talk:1-2-3-4

A stabilization smaller by 3 rows and 3 cells is possible:

.....O.....
....O.O....
...O.O.O...
...O...O...
OO.O.O.O.OO
O.O.....O.O
...OOOOO...
.....O.....

Also, a half-cloverleaf makes for a yet denser casing (30 cells, 9x8):

...O.O...
.OOO.OOO.
O...O...O
O.O...O.O
.OO.O.OO.
.........
.OOOOOOO.
.O..O..O.
