Using this approach I have now investigated another 60 4-color 1-D totalistic CA.
23 of these 60 codes yielded interesting behavior:
4193,4194,4195,4638,4641,4643,4648,4737,4738,4742,4743,4745,5266,5267,5268,5271,5276,10514,10515,10519,10521
,10523,10524.
Of particular note are codes 4742, 5268, 10514 and 10524.
