OEIS Sequences

a(n) = n! * ∑_k=1..n-1 1/k!. A38156

Number of distinct resistances that can be produced using at most n equal resistors in series and/or parallel, confined to the five arms (four arms and the diagonal) of a bridge configuration. Since the bridge requires a minimum of five resistors, the first four terms are zero. A174286

Number of unordered rooted trees where each subtree from given node has the same number of nodes. A127524

Intrinsic 9-palindromes: n is an intrinsic k-palindrome if it is a k-digit palindrome in some base. A60879

T(n,k)=Number of (n+1)X(k+1) 0..3 arrays with every 2X2 subblock having nonzero determinant and having the same number of clockwise edge increases as its horizontal and vertical neighbors. A205768

Centered 13-gonal numbers. A69126

Number of partitions of n with rank a multiple of 3. A328988

Triangle read by rows: T(n,k) is the number of weighted lattice paths B(n) having a total of k uhd and uHd strings. A247294

Triangle read by rows: T(i,j) for the recurrence T(i,j) = (T(i-1,j) + 1)*i. A121662
