if x

if y

if –

if (x) — (y)

if (y) — (x)

if (x) —— (y)

when and how x + y might link is interval based, no?

lets put all 3? (top to bottom for now)

{if (x2y — yx —- y)}

if —

if —-

if — x

if — y

(from bottom)

if yx

or

if –2-yx

How x and y link is based on the intervals in the sequence. eg if -x and if -y where x y are on the same interval spot in the sequence – then they will bang head-on, etc..
