6/9 constructor

Choose two pairs with the same tf, transform them through F7+, and immediately obtain one of the two parallel 6/9 classes.

F7+elliptic operations whose result is another pair
?

The ± signs select one of the two lifts of a pair to E_T. Point coordinates stay hidden: F7+ converts the result back into a projective pair.

Placement in the squaretwo parallel progressions
?

Equal tf values match the progression differences. The selected formula recovers the common coordinates E,x,y and thereby satisfies the remaining placement conditions.
