As I understand, A is applicable only to the cases where the dimension
of tuples is fixed while B is perfectly fine for tuples with variable
dimensions (what I'm currently interested in).

Does B apply to Pascal triangle?
The 5-th term corresponds to the tuple [0,0,5], what it is in Pascal triangle?
