%N Joint-rank array of the numbers j*e^(i-1), read by antidiagonals.

%C Joint-rank arrays are defined in the first comment at A182801. (Column 1)=A117869. Every positive integer occurs exactly once, so that as a sequence, A182833 is a permutation of the positive integers.

%F T(i,j)=SUM{floor(j*e^(i-n)): n>=1}.

%e Northwest corner:

%e 1....2....4....5....6...

%e 3....7...12...15...19...

%e 10..21...34...44...55...

%e 30..61...94..124..155...

%Y Cf. A182801.
