BUG+3: [5]r1c8, [7]r7c2, [9]r7c5

(5)r1c8 - r8c8 = (5)r7c9
(7r7c2 - (7=5)r7c9
(9)r7c5 - (9=7)r7c3 - (7=5)r7c9; r7c9 <>7; stte

According to the grid above I can't see xyzw-wing actually referred as wxyz. The hinge cell r7c2 must contain four candidates wxyz.

xyzw stands for xyz wing

wxyzw could be used for the wxyz wing
