Extension!

(x),(0,0,1)(y) = (x),(0,x)(y), (x),(1,0,1)(y) = (x),(0,(x), (0,x)(y)) (y), etc.

(x),(0,1,1)(y) = (x),(x,0,1)(y), (x),(1,1,1)(y) = (x),((x), (x,0,1)(y),0,1) (y), etc.

We can continue with (x),(0,2,1)(y), (x),(0,3,1)(y), etc.

Then we can define the (x),(0,0,2)(y) family as a nest of the (x),(0,x,1)(y) family, and then we can define the other families as it follows.

Then, we can make a 4-entry array, 5-entry array, n-entry array, etc.

The limit is (x),(0,0,0,...,0,0,1)(y)

(sorry, it was too lazy at the moment.)
