Hi rjamil,
Leren's and Cenoman's solutions are indeed WXYZ-Wings, and even Steve's is a transported one. Only mine isn't.
A somewhat related observation: all three of the presented WXYZ-Wings can be expressed as one-link AICs:
I wonder if that's a property of all (UVW)XY(Z)-Wings. I know it's not true for all other ALS-XZs.

(869)b7p739 = (38)r7c38 => -8 r7c2,r9c79 | Leren's

(31)r78c1 = (283)r7c128 => -3 r7c3 | Cenoman's

Hi SpAce,
Thanks for the clarification.
Actually, I wrongly quoted your solution instead of Cenoman OTP solution for which, accept apologies.
Just checking all possible WXYZ-Wing moves routine in my solver for fitness and found lot of OTP WXYZ-Wing moves similar to them.
However, it is difficult to understand such moves in eureka format without mentioning name if any.
