Numerators of secondary Bernoulli twin numbers.Secondary Bernoulli twin numbers are 1, 0, -1/2, -1/2, -1/6, 1/6, 1/6, -1/6, -3/10, 3/10 (twins from -1/6).Consider increasing Bernoulli twin (numbers) polynomials: 1; -1/2, 1; -1/3, 0, 1; -1/6, -1/2, 1/2, 1; -1/30, -1/2, -1/2, 1, 1; 1/30, -1/6, -1, -1/3, 3/2, 1; 1/42, 1/6, -1/2, -5/3, 0, 2, 1; -1/42, 1/6, 1/2, -7/6, -5/2, 1/2, 5/2, 1; -1/30, -1/6, 2/3, 7/6, -7/3, -7/2, 7/6, 3, 1; 1/30, -3/10, -1/3, 2, 7/3, -21/5, -14/3, 2, 7/2, 1; secondary Bernoulli twin numbers are second column terms.a(n) is second column numerators.See A129378,A129826, May 28 1, -1, 2, -2, 0, 6. |
