De Vaucouleurs Atlas Description:

The classification of this galaxy is actually reasonably discernible in spite of the high inclination . The core is very small, and the form of the spiral arms suggests that there might be at least a weak bar in the inner regions. There is a hint of this feature above the main near-side absorption lane near the small nucleus, and also 2MASS images (Jarrett et al. 2003) suggest there might be a bar. NGC 4666 is known as the ``superwind galaxy" (Persic et al. 2004; Walter, Dahlem, and Lisenfeld 2004), owing to the detection of significant gaseous outflow. These detailed studies have indicated that NGC 4666 is an AGN/starburst galaxy that is suffering a gravitational interaction with nearby NGC 4668 .
