The main objective of this paper is to introduce and investigate new number
families derived from finite sums running over divisors and totatives and
containing higher powers of binomial coefficients. Especially, by making
decomposition on the generating functions for a kind of combinatorial number
families recently introduced by Simsek [29], we also construct generating
functions for the newly introduced number families. For symbolic computation
of the newly introduced number families and their generating functions, we
also give computational implementations in the Wolfram language. By these
implementations, some tables of both these number families and their
generating functions have been presented for some arbitrarily chosen special
cases. Additionally, we provide some applications regarding the Thacker?s
(totient) function. In particular, by making summation on all totatives of a
positive integer, we investigate some special finite sums containing both
the Thacker?s (totient) function and higher powers of binomial coefficients.
By this investigation, some of the problems regarding these finite sums have
been partially answered accompanied by some remarks. Furthermore, we propose
an open problem regarding a potential relation between one of these number
families and a formula involving the M?bius function. Finally, the paper
have been concluded by providing an overview on the results of this paper
and their potential usage areas, and by making suggestions regarding future
studies able to be made.
