Appears in sequences

• a(1) = 2; a(n+1) is the smallest prime > a(n) which differs from it in every digit.at n=38A068853
• a(n) is the smallest positive integer not yet in the increasing sequence that is obtained when the largest digit from a(n-1) is deleted and the remaining digits are permuted such that no digit in a(n) has the same position it had in a(n-1) (counting from left to right). No repeated digits allowed; a(1)=10.at n=23A302095
