Survival data [for initial conditions in code 20]

The number of steps for which the pattern produced by each of the first 1000 initial conditions in code 20 survive are indicated in the picture below. 72 of these initial conditions lead to persistent structures. Among the first million initial conditions, 60,171 lead to persistent structures and among the first billion initial conditions the number is 71,079,205.
