By coincidence, I was contemplating adding a comment:
A050289 Zeroless pandigital numbers: numbers containing the digits 1-9 and
no 0's.
The first 9!=362,880 terms of this sequence are Permutations of the digits
1-9 (restricted such that each digit appears exactly once) with
a(9!)=987654321.
A similar comment might be made for A050278.
