Concept
Is H reflexive?
Stephen Davies, Ph.D. Version 2.2.2 Through Discrete Mathematics A Cool Brisk Walk / Chapter 1
"H is an endorelation on T, defined as follows: { (Kirk, Kirk), (Spock, Spock), (Uhura, Scotty), (Scotty, Uhura), (Spock, McCoy), (McCoy, Spock), (Scotty, Scotty), (Uhura, Uhura) }. H is not reflexive because it is missing (McCoy, McCoy)."
