OEIS Sequences

a(n) = 1 + ∑_k=2..n (-1)^k * k² * a(floor(n/k)). A361983

Number of distinct products i·j*k with 1 <= i < j < k <= n. A27430

a() = 1,3,... [ A037257 ], differences = 2,... [ A037258 ] and 2nd differences [ A037259 ] are disjoint and monotonic; adjoin next free number to 2nd differences unless it would produce a duplicate in which case ignore. A37257

Numbers obtained by reinterpreting base-2 representation of n in A001563-base (A276326): a(n) = ∑_k>=0 A030308(n,k)*A001563(k+1). A276091

Number A(n,k) of squares in all tilings of a k X n rectangle using integer-sided square tiles; square array A(n,k), n>=0, k>=0, read by antidiagonals. A226545

T(n,k)=Number of (n+2)X(k+2) 0..3 arrays with every 3X3 subblock row and column sum 2 4 5 or 7 and every diagonal and antidiagonal sum not 2 4 5 or 7. A251923
