Meertens Number And Its Variations, Chai Wah Wu
Meertens Number And Its Variations, Chai Wah Wu
Communications on Number Theory and Combinatorial Theory
In 1998, Bird introduced Meertens numbers as numbers that are invariant under a map similar to the Gödel encoding. In base 10, the only known Meertens number is 81312000. We look at some properties of Meertens numbers and consider variations of this concept. In particular, we consider variations of Meertens numbers where there is a finite time algorithm to decide whether such numbers exist, exhibit infinite families of these variations and provide bounds on parameters needed for their existence.

Generating B-Nomial Numbers, Ji Young Choi
Communications on Number Theory and Combinatorial Theory
This paper presents three new ways to generate each type of b-nomial numbers: We develop ordinary generating functions, we find a whole new set of recurrence relations, and we identify each b-nomial number as a single binomial coefficient or as an alternating sum of products of two binomial coefficients.
