I never heard of vampire numbers before I checked this note. Ninety-nine is an excellent score.

A vampire number is a composite natural number with an even number of digits, that can be factored into two natural numbers each with half as many digits as the original number, where the two factors contain precisely all the digits of the original number, in any order, counting multiplicity12345. The two factors are called the fangs235. To be classified as a vampire number, the fangs must contain the same digits as the original number and have half the number of digits35.
