All terms in the sequence contain 0.
The fact that all digits in the terms are distinct makes the sequence finite.
In fact, the sequence contains 59 terms and a(59)=901325476.
The terms that require the smallest number of permutations to recover their natural ordering are a(1)=10, a(9)=1023 and a(35)=1023456 (one permutation required).

EXAMPLE
a(2)=230 since it is the smallest positive integer not yet in the sequence that is obtained when the largest digit 1 from a(1)=10 is deleted, the remaining digit 0 is permuted from the second to third place, and no digits are repeated.
