This C1-symmetric (2+2)G collision shows extremely complex dynamics even after 7.7M generations.

Conjecture: for any asymmetric initial configuration "of the kind shown above"* that remains C1-symmetric throughout its evolution, there is a generation G such that for g>G, the population of at least one of states 1 and 2 has an upper bound.
In essence, this means that for the above example, state 2 would eventually fully encapsulate state 1, so state 1 would not be able to send off any more gliders or grow beyond a maximum population.

*This is ill-defined, I know, but you get the gist. No point in putting one prime-number generator of each state and a puffer so they don't interact and grow infinitely.
