Triangle of numbers related to cellular automata.
It appears that this is also a triangle read by rows in which row n lists the first 2^(n-1) terms of A255046, with n >= 1.

Examples

			Written as an irregular triangle in which the length of row j is 2^j, j >= 0, the sequence begins:
1;
1,2;
1,2,3,4;
1,2,3,4,3,6,9,8;
1,2,3,4,3,6,9,8,3,6,9,10,11,20,25,16;
1,2,3,4,3,6,9,8,3,6,9,10,11,20,25,16,3,6,9,10,11,20,25,18,11,20,27,30,41,64,65,32;
...
It appears that the right border gives A000079.
It appears that the row sums give A007582.
It appears that rows converge to A255046.
