Sets of 5 queens that dominate the 8x11 chessboard except for one square

There are 8 different solutions; this file contains 8 of them.

Legend:
Sym (H) denotes reflection symmetry across the horizontal bisector.
Sym (V) denotes reflection symmetry across the vertical bisector.
Sym (C) denotes central symmetry about the center of the board.
Sym (D+) denotes reflection symmetry across the diagonal from lower left corner of the board.
Sym (D-) denotes reflection symmetry across the diagonal from top left corner of the board.
Sym (90) denotes 90 degree rotational symmetry about the center of the board.
The Sym (.) strings are printed without space next to the tables to help searching the solutions.

Δ denotes the absolute value of the difference of the number of queens on dark squares and of the ones on light squares.
