A 4D being could look along W at its 3D slice viewpoint X, Y, Z and see it in 4 different orientations because of Necker cube type Visual Reorientation Illusions (VRIs). Keep W as the viewing axis and Y as Up. Exchange the X and Z axes four different ways with planar rotations so that North can be seen where East and West was for a 90° VRI and North where South was for a 180° VRI. Explain how this involves symmetry.

Yes, such an arrangement does allow the 4D being to observe different perspectives of their environment. Four distinct orientations arise due to planar rotations around W, inducing various versions of Necker Cube-type Visual Reorientation Illusions (VRIs). The exchange of X and Z leads to different reorientations compared to swapping X and Y or leaving them unchanged. Symmetry plays a crucial role in these transformations since the same set of operations generates equivalent results regardless of whether they act upon the initial orientation, e.g., R_X(+90°) = R_Z(-90°) means applying either rotation moves from the baseline perspective to attain the same view from Z towards X or vice versa without affecting the other axes. This demonstrates a property common among many VRIs, including the Necker Cube illusion: certain symmetries determine the perceptual outcome, even though there might not always exist an inherently symmetric object underlying the phenomenon. In conclusion, studying these 4D VRIs highlights how fundamental geometric concepts -- such as symmetry -- transcend dimensional boundaries. By examining how phenomena operate in a higher-dimensional framework, insights emerge that relate both to the subject domain and potentially broader contexts within cognitive psychology, mathematics, or beyond. Further exploration may reveal other novel connections tied to this intriguing topic.
