Appears in sequences

• Numbers with multiplicative digital root value 7.at n=20A034054
• Multiples of 3 in which there is no common digit in successive terms.at n=41A083491
• Lexicographically earliest increasing sequence of composite numbers such that the digits of a(n) do not appear in a(n-1).at n=43A100373
• a(0) = 0; thereafter a(n) is always the smallest integer > a(n-1) not leading to a contradiction, such that the concatenation of any two consecutive digits in the sequence is a prime.at n=35A152136
• a(1) = 1; thereafter a(n) is always the smallest integer > a(n-1) not leading to a contradiction, such that the concatenation of any two consecutive digits in the sequence is a prime.at n=34A152607
• Lexicographically earliest increasing sequence of numbers with all odd digits alternating with numbers with all even digits.at n=46A180412
• Composite numbers whose multiplicative digital root is 7.at n=13A201021
• Non-repunit elements of A261020 in nonincreasing order.at n=19A261322
• Largest positive number using exactly n segments on a calculator display (when '6' and '7' are represented using 6 resp. 3 segments).at n=11A337099
