OEIS Sequences

Multiples of 4 whose digits add to 4. A63997

Consider a decimal number of k >= 2 digits m = d_k*10^k-1 + d_k-1*10^k-2 + ... + d₂*10 + d₁. a(n) is the least number m such that the n-th iteration of the transform T(m) -> (d_k + d_k-1 mod 10)*10^k-1 + (d_k-1 + d_k-2 mod 10)*10^k-2 + ... + (d₂ + d₁ mod 10)*10 + (d₁ + d(k) mod 10) returns m, or -1 if no such number exists. A243993

Integers whose decimal representation consists of three distinct digits, one appearing once, one appearing twice, and one appearing three times. A182040

5-Smith numbers. A103126

Smallest k such that the concatenation 123...(k-1) k (k-1)...321 ( a concatenation of natural numbers from 1 to k and back to 1) is a multiple of prime(n), or 0 if no such number exists. A77187

Positive numbers k such that k and 2·k are anagrams of each other in base 3 (k is written here in base 3). A23058
