OEIS Sequences

For every positive integer m, let u(m) = (d(1),d(2),...,d(k)) be the unitary divisors of m. The sequence (a(n)) consists of integers of the form d(k)/d(1) + d(k-1)/d(2) + ... + d(k)/d(1). A229999

Triangle read by rows: T(n,k) = 4·T(n-1,k-1) + T(n,k-1) with T(2·m,0) = 0 and T(2·m+1,0) = 5^m. A292466

Zeroless numbers n such that n and n - (product of digits of n) are both palindromes. A229761

Palindromes in which the sum of the internal digits = the sum of the external digits. A88285

Palindromes of the form 4n + 1 that are divisible by 5. A256704

Number of (n+1)X(2+1) 0..3 arrays with 2X2 edge jumps all no more than +1 in one of the clockwise or counterclockwise directions or both. A234754
