I managed to make one of the pre-TLs:

`x = 50, y = 42, rule = B3/S23`

EDIT: So a possible plan could be to add the following sparks at generation 16:

`x = 44, y = 27, rule = LifeHistory`

EDIT2: Sorry, there's nothing wrong with the more common TL predecessor either:

`x = 44, y = 28, rule = LifeHistory`
