An easy solution is a w-wing(67)r5c8|r7c6 SL(7)r59c5 plus transport
(6=7)r5c8-r5c5=r9c5-(7=6)r7c6-r7c9=r8c7; -6r4c7

A fun solution was a AUR(17)r36c12 external SIS : (1)r3c4, (7)r1c2, (7)r6c6
(1)r3c4-r9c4=(1-7)r9c5=r79c6-r56c6=r5c5-r5c8=r3c8;
(7)r1c2;
(7)r6c6-r79c6=r9c5-r9c7=r4c7-r5c8=r3c8; -7r3c12

Ted, I can't make heads nor tails of the transport. I can see a simple transport from r7c6 to r8c7 that makes the elimination, but I don't see from the notation what roles r5c5 and r9c5 play in the transport or how it works if the transport starts with r5c8. Question

Marty, Sorry for the delay in responding to your post but I was traveling on vacation again.

Cells r5c5 and r9c5 form the strong link on (7). The first four entries in the posted AIC form the w-wing(67) and the last two entries are the transport.

Thanks Ted. Obviously I made the silly mistake of thinking that everything following the words "plus transport" referred just to the transport. Embarassed
