Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

nevermind, I realized the number itself has to be a prime.
why is 522 not included on the list since it can be split in 5, 2, 2 (all primes)? I see plenty of numbers between 500 and 600 that can be considered total primes because all of their digits are primes but they're not on the list, what am I not seeing?
