%N The k-sequence associated with A125153.

%C A permutation of the positive integers.

%F This sequence k(m) is associated with the array T(3,2,1) at A125153 as follows: row m consists of numbers of the form Floor[(3^p)/(2^k)] for k=k(m).

%e The pairs (j,k) for the first six rows are

%e (1,1), (2,2), (3,3), (4,4), (5,5), (7,8).

%e First term in row m is Floor[(3^j(m))/(2^k(m))],

%e so for m=1,2,3, the first terms are

%e 1=[(3^1)/(2^1)], 2=[(3^2)/(2^2)], 3=[(3^3)/(2^3)].

%Y Cf. A125153.

%K nonn
