Talk:1-2-3-4

A stator 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.

Hmm, the wiki already has a 28-glider synthesis, though...? Apple Bottom (talk) 22:42, 14 August 2017 (UTC)

Whoops, sorry, I accidentally thought that the original form of 1-2-3-4 was different and had a different stator, and I also missed the synthesis file that was already there. So just ignore the above rle. Goldtiger997 (talk) 22:51, 14 August 2017 (UTC)

No worries. Thanks anyway! *tips hat* Apple Bottom (talk) 21:17, 15 August 2017 (UTC)
