FORMULA
|
This sequence k(m) is associated with the array T(3,2,1) at A124153 as follows: row m consists of numbers of the form Floor[(3^p)/(2^k)] for k=k(m).
|
|
EXAMPLE
|
The pairs (j,k) for the first six rows are
(1,1), (2,2), (3,3), (4,4), (5,5), (7,8).
First term in row m is Floor[(3^j(m))/(2^k(m))],
so for m=1,2,3, the first terms are
1=[(3^1)/(2^1)], 2=[(3^2)/(2^2)], 3=[(3^3)/(2^3)].
