By coincidence, I just watched this video on this same topic: https://m.youtube.com/watch?v=5oULEuOoRd0

The visualizations and the real problem solving demonstrated made it much easier (for me) to intuitively understand than any amount of reading

Something about this doesn't make sense - from the C=A case:

> we wouldn’t be able to tell the difference in results between only doing option B (doubling the butter) and doing all three options: adding an egg, doubling the butter, and adding nuts on top.

However, the experiments listed include exactly those 2 experiments (Test 1 and Test 3 in the table with a column titled C=A), so unless I'm missing something, "wouldn't be able to tell the difference" doesn't mean what I expect it to.

I have studied at least a little combinatorics, and the language here is completely inpenetrable to me. Neither the question of "what property is this design supposed to have?" or "why does it have it?" are stated in plain or even mathematical english. The wiki entry is similarly unhelpful.
