Can we construct a breeder, that supports the following formula:
p_t = 1/2 t^2 + 1/2 t + p_0
or
p_t = t^2+p_0?
(in these cases, t is the generation, and p_t means the population of the populations of generation t. especially, p_0 is the initial population.)

Just for fun, I'm looking for a spaceship who's back and front works exactly like a copperhead, but is larger, sort of like this but its connected to itself.

I think cottonmouth does.

I finally realized that the "odd-midline" option search for a width 2n+1 spaceship in LSSS(n is the margin).
so that's why Anura is actually 33 cells wide instead of 31 cells wide.
