OEIS Sequences

a(n) is the smallest number which can be represented as the sum of n distinct nonzero n-gonal pyramidal numbers in exactly n ways, or -1 if no such number exists. A350397

a(n) is the number of distinct solution sets to the quadratic equations u·x² + v·x + w = 0 with integer coefficients u, v, w, abs(u) + abs(v) + abs(w) <= n having a nonnegative discriminant. A379597

Number of vertices in a regular 2n-gon when all vertices are connect by straight lines except for the n lines joining diametrically opposite vertices. A368814

σ(n) plus the n-th prime gives a cube. A114081

O.g.f. A(x) satisfies: [xⁿ] exp(n·A(x)) * (1 - n·x - n·x²) = 0, for n > 0. A321086

a(0) = 397; a(n+1) = a(n)² if a(n) is prime, floor(a(n)/2) otherwise. A376801

Number of discrete implications I : L_n² -> L_n defined on the finite chain L_n = {0,1,...n} which satisfy the consequent boundary, i.e., I(x,y) >= y for all x,y in L_n. A367540
