AUR (38)r34c89 with x-wing 8 overlay; r34c8<>3 which sets up a
w-wing13 r6c7 & r7c6 with SL3 in r257c8
(3)r2c8 -r3c9=r4c9-(3=1)r6c7
(3)r5c8-(3=1)r6c7
(3)r7c8-(3=1)r7c6; r6c6<>1
Almost w-wing (AW-wing) 13 in r1c2 & r2c8 and SL3 in r7c28 with fin (4)r2c8
If w-wing is true: r2c13<>1
If fin is true: (4)r2c8-(4=3)r1c7-(3=1)r1c2; r2c13<>1
RP34 r1c7 & r7c2; r1c2<>3 plus after cleanup,
transport (3)r7c2-r5c2=(3)r5c8; r2c8<>3
transport (3)r7c2-r9c3=(3)r9c4; r1c4<>3
ANP(34=7)r78c2-(7=3)r9c3{*M}-r9c4=r8c45-r8c7=r1c7-r1c5=r2c45-r2c13=r3c23-(3)r3c3{*M}=(3)r3c2; r45c2<>3
I believe that my last step is valid using an earlier step to make a later deletion, but I do not know how to properly notate the move. Comments appreciated.
