Query: Maximal Independent Sets in Polygonal Cacti   Counting the number of maximal independent sets of graphs was started over
$50$ years ago by Erd\H{o}s and Mooser. The problem has been continuously
studied with a number of variations. In this paper, we applied the concept of
bivariate generating function to establish the recurrence relations and their
asymptotic behavior of the number of maximal independent sets of regualr
$n$-gonal cacti when $3 \leq n \leq 6$.
