User blog comment:Kite in rainbow/Kite in rainbow's bracket-comma notation,it can easily beyond ψ(I)!/@comment-5529393-20160210032429

A few more questions:

1. You mention x-1,x-k,M-1,N+1, do you mean add to or subtract from the rightmost number of the BCS?

2. In the line h=h_1,h_2,...,h_n=a_1,a_2,...,a_k-1,M,0,...,0, what is a_k-1, is it a_{k-1}, or a_k decremented by 1?

3. What is M?  Is it the bracket that contains z?
