The top left corner of the array A265609 with its terms shown in factorial base (A007623) looks like this:
1, 0, 0, 0, 0, 0, 0, 0, 0
1, 1, 10, 100, 1000, 10000, 100000, 1000000, 10000000
1, 10, 100, 1000, 10000, 100000, 1000000, 10000000, 100000000
1, 11, 200, 2200, 30000, 330000, 4000000, 44000000, 500000000
1, 20, 310, 10000, 110000, 1220000, 14000000, 160000000, 1830000000
