De Vaucouleurs Atlas Description:

The structure of this galaxy is interesting in that a well-defined Arm Class 3 spiral (Elmegreen and Elmegreen 1987) is imbedded within a very bright background disk. The very small core and basic structure of the spiral are our basis for the Sc classification.

NGC 1792 is thought to be interacting gravitationally with its close neighbor, NGC 1808 . The HII region distribution and radio continuum emission in NGC 1792 were studied by Dahlem, Bomans, and Will (1994), who suggested that the interaction has triggered propogating star formation in the disk.
