You don't see one for weeks and then two come along in an evening...

I’ll borrow some of that 39 action (don't know if this grid helps or not Marty):
(NOT 3)r3c1=(3-9)r3c7=r9c7-r9c2=(9-3)r1c2=(3)r3c1
Chain/loop is shown in green r3c1 => 3

A flightless xy-wing also does the trick.............
Quote: | Flightless xy-wing 34-9 with vertex 34 in r3c1 plus transport: (9)r3c8 - r78c8 = (9)r9c7; r9c2<>9 |
