Appears in sequences

• Numbers with multiplicative digital root value 3.at n=28A034050
• a(n) = (10^n + 17)/9.at n=8A098406
• Keep only the first digit of each integer and concatenate them. The result is the concatenation of all integers of the sequence.at n=35A106000
• Start with a(1) = 1. For n>1, choose a(n) to be the smallest number > a(n-1) consistent with the condition that "the a(n)-th digit is a 1" is true for all n.at n=45A114134
• Composite numbers with digital product = 3.at n=16A199982
• a(n) is the smallest proper multiple of n whose digit product is the same as the digit product of n; 0 if no such number exists.at n=30A340204
