High density spaceships

[Rhombic]

Ideally for spaceships with only one dead cell (or an otherwise remarkably low number thereof) within its bounding box in its densest phase.

17/18 live cells in densest phase, a c/9:

Code: Select all

x = 6, y = 3, rule = B2i3-ckr4iqt5ij6en7e/S2aek3aeikn4ajktyz5-ejkq6-cn7e
6o$4obo$6o!

Code: Select all

x = 4, y = 3, rule = B2-an3qr4ajkty5ejkqr6-en7/S12cen3-ajq4cjknz5-eij6-ei7e8
4o$ob2o$4o!

Another highest density 3c/35 with a very immature phase.

Code: Select all

x = 9, y = 16, rule = B2k3-cr4eiq5aeqr6in7e/S02ek3acein4ajt5ceiy6ac7e
b4o$b2obo$b4o9$b2o$o2b5o$b2o5bo$o2b5o$b2o!

[muzik]

Highly dense 2xn photons:

Code: Select all

x = 6, y = 14, rule = B1e3a/S2a4ar5i
4b2o$3b3o3$3b3o$2b4o3$2b4o$b5o3$b5o$6o!

and a 3x3 one:

Code: Select all

x = 3, y = 3, rule = B1e5i/S2a4r7e
3o$b2o$3o!

2x3:

Code: Select all

x = 2, y = 3, rule = B1e5i/S2a
2o$bo$2o!

c/2 version of above:

Code: Select all

x = 2, y = 3, rule = B2c3a5i/S2a3e
2o$bo$2o!
