Here, a number is considered pandigital in base b if any digit from 0 to b-1 appears at least once in its base b representation (ignoring leading zeros).
This is a subsequence of A000225, conjectured to be finite (no other term below 2^1000000).
No other terms below 2^10^10. - Charles R Greathouse IV, Sep 26 2016

EXAMPLE
32767 is not pandigital in any base b between 2 and 6:
b 32767 in base b Missing digits
- --------------- --------------
2 111111111111111 0
3 1122221121 0
4 13333333 0, 2
5 2022032 1, 4
6 411411 0, 2, 3, 5
Moreover, 32767 is too small to be pandigital in any base b > 6, hence 32767 is in the sequence.
