[y.kohmoto]

    Hi, Seqfans

    Reading the mails from Seqfan mailing list, I have understood something
interesting related with Bernoulli Number was  discovered.
    But I don't understand well.
    What is Bernoulli number?
    Why do they think A001067 and A046968 should be same?
    Someone please explain them to me , and tell me a good book of Bernoulli
Number.

    I must say I am an amateur  mathematician.
    What I know about Mathematics is what I learned in high school.
