Appears in sequences

• Primes with consecutive (ascending) digits.at n=9A006055
• Duplicate of A006055.at n=9A006510
• a(n) is an n-digit number with digits in increasing order with 0 following 9 and this is maintained in the concatenation of any number of consecutive terms.at n=5A062273
• a(1) = 1; for n > 1, a(n) = largest prime divisor of A062273(n).at n=5A077576
• Let S = 12345678901234567890123456..., the cyclic concatenation of digits; partition this string into distinct squarefree numbers. To avoid leading zeros, no member may end with the digit 9.at n=26A085944
• Smallest available integer which fits into the repeating pattern 0123456789.at n=38A098755
• Slowest increasing sequence with its first 10 digits all different one from another, then the next 10, then the next 10, etc.at n=43A106604
