Chris Bird is developing its notation for several years, put a lot of work to it and here is the result: busy beaver first-order to easily beat his record holder. I think Chris will have to write a thousand pieces of his notation for large numbers to get to the function that will be able to beat such as BB (500) of the first order.

Vithagoras, good job!
