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.

ah shit. You are right, thanks a lot!
The hyperfactorial above and equal 6 is not right guys? It is not even possible that is has the same length of digits (78371783) as H(5). The solution 4031078400000 should be right. I got a mistake message even tho, my code was right.

This doesn't work if, there is no "True" in the list. This code gives you a None and a None is not a 0. Like they want it in the test.
did not anybody solve that with the replace() function?
I like your solution... very clever
