I'm being lazy.
(4)r3c1 = (41-3|7|8|9)r3c79 =singles>= !UR(26)r49c79! => +4r3c1; stte
The weird =singles>= strong link means that the strong link itself is valid both ways, as it should be, but the 'singles' qualifier only works from left to right. For that reason I wanted to use an implication instead of a strong link, but it doesn't make sense because of the preceding weak link. Perhaps it would be clearer to write the whole thing as an implication chain to avoid that complication:
-4r3c1 -> 14r3c79 -> -(3|7|8|9)r3c79 ->singles-> !UR(26)r49c79! => +4r3c1; stte
(Then again, if that's reversed the 'singles' qualifier must be dropped.)

That one requires more than mere fish, even finned. It is also not enough to add (3D) bivalue-chains. But z-chains are enough.
