Most sources off the net say it's In My Arrogant Opinion... (I have to resort to those acronym definition sites all the time so it's easy to find such a definition).

I don't quite think so. a(5) is 694, but 694 in base 4 doesn't contain the digit 0. It's simply the first pandigital number in base n. If those two sequences were coincidental, it would be something...

It's not the official answer, but as with all of these sequence puzzles there may be some logic behind your reasoning, even though it's not correct. Would you like to explain it?

If n is prime, then 2^{n-1} \equiv 1 (mod n), so 2^n \equiv 2 (mod n).

If n is even, then 2^n (mod n) is obviously even.

So n (if it exists) must be an odd composite. Pretty sure you had...

z = \prod_{n=1}^ip_n

Then these (and exactly these) factors may be present in x and y. Without loss of generality, assume that:


x = \prod_{n=1}^jp_n


y = \prod_{n=j+1}^ip_n
