I couldn't figure out how to notate this on one line.

(4=3)r5c7-(3=5)r5c4-(5267=14)r123c4, r1c56-4r1c8=4r3c8.

There are now pincers at r3c8 and r5c7. Transport r5c7 to r1c6 via r5c6=>r1c8,r3c5<>4

"Reverse" the transport and put it at the front: (4) r1c6 = r5c6 - (4=3)r5c7-(3=5)r5c4-(5267=14)r123c4, r1c56-4r1c8=4r3c8

Leren, Thanks. I tried to do something along those lines but obviously veered off in the wrong direction somewhere.
