Comment(s):

Though the cover of the issue denotes this as an "Imaginary" Story, it is not so noted in the story itself. The events having occurred on Krypton do not follow with previous or later established history, such as Brainiac's taking of Kandor prior to the marriage of Jor-El and Lara and Luthor's appearance on Krypton is never mentioned again. Therefore, it's likely Luthor shifted into another universe while traveling to the past.

In Crisis on Infinite Earths: Absolute Edition (November 2005), this was determined to have occured in the universe of "Earth-170."

A race of unseen aliens responsible for most of the crime on Krypton was also presented in Action Comics #332/2 (January 1966): "How Superwoman Trained Superboy!" an "Imaginary Story" later retconned to have occurred on Earth-332. Appropriately named "The Invisibles" these aliens hailed from a dimension bordering that universe's Krypton.
