OEIS Sequences

a(n) = 4·n² - 3·n + 1. A54552

Number of sets in the geometry determined by the Hausdorff metric at each location between two sets defined by a complete bipartite graph K(4,n) (with n at least 4) missing three edges, where all three removed edges are incident to different vertices in the 4-point set but all three removed edges are incident to the same vertex in the other set. A340433

Number of sets in the geometry determined by the Hausdorff metric at each location between two sets defined by a complete bipartite graph K(4,n) (with n at least 4) missing three edges, where all three removed edges are incident to the same vertex in the 4-point set. A340899

One of many square spiral sequences: a(n) = n² + n - floor((n-1)/2). A317186

Goodstein sequence starting with 4: to calculate a(n+1), write a(n) in the hereditary representation in base n+2, then bump the base to n+3, then subtract 1. A56193

Composite and every divisor (except for 1) contains the digit 2. A62664

Numbers k such that φ(k) = φ(k+2). A1494

Triangular matrix T, read by rows, that satisfies: SHIFT_LEFT(column 0 of T^(2·p-1/2)) = (2·p-1)*(column p of T), or [T^(2·p-1/2)](m,0) = (2·p-1)*T(p+m,p+1) for all m>=1 and p>=0. A105615

Convolution of A001045(n+1) (generalized (1,2)-Fibonacci), n >= 0, with itself. A73371

T(n,k)=Number of (n+1)X(k+1) 0..1 arrays with nondecreasing x(i,j)+x(i,j-1) in the i direction and nondecreasing absolute value of x(i,j)-x(i-1,j) in the j direction. A250783
