some of them are the same as in Life, but a couple of them are different. Unfortunately there is no glider turning reaction as in life and no 2G collision for the replicator.

However, there are plenty of 3G collisions for the replicator, a one sided option:

`x = 24, y = 10, rule = B36/S23`

3G for the p7 and p10:

`x = 43, y = 16, rule = B36/S23`

In contrast to Life we have some 3G collisions which output 3G, here 2 examples:

`x = 97, y = 44, rule = B36/S23`

The first one has the same output direction as the input, just rotated by 90°.

3G for a bomber + block:

`x = 24, y = 25, rule = B36/S23`

Thus, we have a 4G synthesis for the bomber (but there might exist a 3G option):

`x = 34, y = 47, rule = B36/S23`
