COMMENTS
Joint-rank arrays are defined in the first comment at A182801. As for any joint-rank array, A182949 is a permutation of the positive integers, but, a fortiori, A182949 is an interspersion: after initial terms every row is interspersed with all other rows. The numbers (3*i+1)*3^j as an array comprise A182828; and sorted, A026225.
(row 1)=A007051.
(row 2)=A052919.
(col 1)=A182829.
