Speaking of explosivity, what if we define explosive in terms of the limit of the percentage of patterns of a specific size that explode? Would that be easy to define, and would it work? I'm thinking "size" should be in bounding box, because cell count can lead to big complicated machines like RCT. ...

I'm pretty sure the fourth number is a hash value based on the population change between generations. This is how it's the same each time even if it appears on a different generation.

Around gens 15-30 this pattern seems to generate a relatively large grey section that looks like part of max : x = 7, y = 10, rule = B3/S23 3bobo$4b2o$4bo2$4b2o$4bobo$obo3bo$o4b2o$o$2bo!

The least frequent 3x3 window seems to be an "off" cell surrounded by eight "new" cells. This makes sense.
