Lacings in CodeBlocks

Today I stumbled upon this notation in codeblocks and I tried to figure out how it works because I couldn't remember any documentations on this particular aspect but I think is pretty useful because it helps having compact clean graphs.

I've used a range from 0 to 5 (I prefer to use the codeblocks for this purpose) and built some points, on the Point.ByCoordinates node there is the lacing strategy to apply but on codeblocks there is not (to be fair now you can assign the lacing strategy to a selection of node via right click, also the codeblocks but it doesn't seemed to work in my case) .

With this syntax though you gain control over the range and how to use it applying transposition directly.

b=Point.ByCoordinates(a< i >,a < j >,a < k >)

Now i,j, and k have to be non negative integers, which means zero is allowed, what this does is to let you control how to combine the numbers in the range.

If i,j and k have the same values then the result will be a list of 6 points where for each point x=y=z.

When these indices are equal to 0 they return the first value of the range (in this case 0), otherwise the indices express the order in which the values in the range are going to be combined: the higher index is the one that goes through all the values of the range first.

When two indices are equals and bigger than  0, for instance 1,1,2 or 2,2,1, the geometric outcomes are going to look the same but the points will be listed differently just like using the transpose node.

When the indices are all different and greater than zero you a have a cross product lacing behavior.

Without further ado, here are some images that can explain better the results of the different combinations.
