• Partition the concatenation 1234567...of natural numbers into successive strings which are multiples of 6, all different and > 6. (0 never taken as the most significant digit.)at n=3A077299
• Smallest multiple of n that is a concatenation of (increasing) natural numbers starting with(n+1).at n=7A077310
• Multiples of 4 that are the concatenation of 4 consecutive natural numbers.at n=1A082242
• Triangle read by rows: T(n,k) = value of the string of length k beginning at position n in the concatenation of natural numbers in decimal representation, 1<=k<=n.at n=42A162711
