COMMENT
|
1. k divides Q(n,k) for each k.
2. The numbers in row n are distinct if and only if n is a term of the Sieve of Tchoukaillon (or Mancala, or Kalahari), A007952.
|
|
FORMULA
|
For n>=1, for k=1,2,...,A082447(n), Q(n,1)=n, Q(n,k)=k*Floor(Q(n,k-1)/k).

First 8 rows:
1
2 2
3 2
4 4 3
5 4 3
6 6 6 4
7 6 6 4
8 8 6 4
For row 5: Q(5,1)=5, Q(5,2)=2*[5/2]=4, Q(5,3)=3*[4/3]=3.
