OEIS Sequences

Let p = n-th irregular prime, A000928(n). Then a(n) = smallest value of m such that numerator(Bernoulli(2·m)/(2·m)) / numerator(Bernoulli(2·m)/(2·m*(2·m-1))) equals p. A92291

Fibonacci sequence beginning 4, 26. A22386

a(n) = 288·2ⁿ - 156. A278128

Triangle read by rows: T(n,k) (n >= 1, 3 <= k <= n+2) = number of k-sided cells in the n-th figure shown in A255011 (meaning the figure with 4n points on the perimeter). A334699

Largest k such that the arithmetic mean of φ(n),φ(n+1),....,φ(n+x) is an integer for any·0<=x<=k. A73572
