FORMULA
|
Continuing the yesterday transformation,used twice, we start like the second example from Bernoulli twin numbers (A129826) with 0 at the upper line . 0 1 1/2 1/6 0 -1/30 0 1/42 0 1 -1/2 -1/3 -1/6 -1/30 1/30 1/42 -1/42 are (upper line) the "conjugated" Bernoulli numbers G(n) . G(0)=0 G(1)=B(0)=1 G(2)=-B(1)=1/2 G(n+1)=B(n) . We multiply by n! n=0.. .The first two differences are 1 0 0 -1 -4 4 120 -120 -1 0 -1 -3 8 116 -240
