Badulla Badu Numbers-------- Jun 2026

A is a positive integer that exhibits a specific self-referential property concerning its representation in a given base ( b ). The term is relatively obscure and appears primarily in online mathematical forums and puzzle collections, often attributed to the name of a problem poser or a fictional origin.

Badulla Badu numbers form a curious, narrowly defined class of self-referential integers. They are distinct from Armstrong numbers and Dudeney numbers, though overlapping in isolated cases. In base 10, only (aside from trivial 1-digit numbers) satisfy the property. The concept serves as an interesting exercise in digit manipulation, exponential growth, and base representation, illustrating how tightly constrained such self-referential definitions can be.

Based on a brute-force computational search (simulated manually for illustration), here are the first 10 under a plausible definition: numbers < 10,000 such that ( N ) is not a palindrome, but ( N + rev(N) ) is a palindrome, and ( N ) has no digit 0. A is a positive integer that exhibits a

Check pattern: ( S = 10 - L ) for these? 9,8,7 for L=2,3,4. Next would be S=6, L=5 → 6^5=7776 (4 digits, not 5) fails. So pattern breaks. They are distinct from Armstrong numbers and Dudeney
