Here's something to look into from the older threads. I just copied and pasted the text from Discord, if you're wondering why it's posed as a question.
Does anyone know why with the "there's always a cell 2n to the right" thing in each row that there seem to be arbitrary starting places? You can always start from (-1,n) and (0,n), but those aren't always the only starting places. Row 3, for example, has (-1,3) and (0,3), which do have cells 6 cells to the right, but (2,3) and (3,3) are also valid, and also have cells 2n to the right each.
