Notes:

• This episode mentioned the Kzinti race, which was a tie-in to "The Slaver Weapon" and to Larry Niven's Known Space Universe.
• This episode's writer, Walter Koenig, originally played Ensign Pavel Chekov on the Original STAR TREK series and also starred in the semi-regular role of Alfred Bester, the highly placed member of Earth's Psi Corps on Babylon 5.
• This episode had a major tie-in with the original series episode "Space Seed" in that Dr. Keniclius was one of the genetic supermen created in the Eugenics war of 1996.
• In this episode, Kirk referred to the concept of IDIC (Infinite Diversity in Infinite Combinations), a tie-in to the original series episode "Is There In Truth No Beauty?"
• In this episode, flying plant creatures menace the Enterprise landing party. The animation drawings of the creature were reused by Filmation artists to create the purple flying lizard-like creatures that menaced the Enterprise landing party in "The Eye of the Beholder". Another example of similar life forms evolving on different planets.
• There is a page in this site that focuses on the Phylosian Ships that were seen in this episode.
• No reasonable explanation was given in the episode for the clones being 25 feet tall.
• This episode had a production error: While Spock was being held captive on the planet's surface, a brief overview shot of the bridge showed Spock at his station.
• Contrary to common belief, in no STAR TREK episode or movie did Captain Kirk ever say, "Beam me up, Scotty." However, in this animated episode he came close when he said, "Kirk to Enterprise. Beam us up, Scotty."
• The Retlaw plant seen in this episode was named for the show's writer. ("Retlaw" is "Walter" spelled backwards).
• A VHS video tape containing "The Infinite Vulcan" and "More Tribbles, More Troubles" is available for purchase from amazon.com, the online bookseller.
• "The Infinite Vulcan" was novelized by Alan Dean Foster in Star Trek Log Two published by Ballantine Books in September 1974. Also novelized in the book was "The Survivor" and "The Lorelei Signal".
