+177 How many ways are there to put 9 differently colored beads on a 3x3 grid if the purple bead and the green bead cannot be adjacent (either horizontally, vertically, or diagonally), and rotations and reflections of the grid are considered the same?
+177 I know that either the purple bead or the green bead can't be in the center of the grid, but I'm basically stuck there.
+177 Also, the purple bead and the green bead can't be in the same 4x4 mini-grid. Does that help?
