"Pandigital numbers" (numbers that contain every digit) might seem random, but let me show you how important and mysterious they truly are. Prepare for pandigital pandemonium, including primes, palindromes, perfect powers, and paradoxical truths about numbers. This is the longest episode on this channel yet and is full of surprises (leave a comment if you see all 3 squirrel cameos!).

Some of the topics in this episode include: pandigital numbers and zeroless pandigital numbers, pandigital prime numbers, pandigital perfect powers such as square numbers, pandigitally “persistent” numbers, “polydivisible” numbers, palindromic numbers, hyperelevens (often referred to as “generalized repunits”), pandigital numbers in other bases like Base 2 (binary), Mersenne primes (the biggest primes ever discovered), ways to compare sizes of infinite things such as “natural density”, and some paradoxical traits about pandigital numbers that I realized when investigating them!
