This data is interesting for what it implies about the origins of large triangles, the prime tiles for tiling the plane according to Rule 110. One thing is that when the triangle is big enough, it has a fringe of T1's, T2's and T3's on top. Empirically, large triangles seem to occur - T12's can be seen without trying hard - but the clusters of triangles appearing in the gliders which have been so far reported never seem to be very big.
