Bell number

[y.kohmoto]

    Hello, seqfans.
    I think Japanese is the most mathematical language.
    Because it has all names of partitions of an 5-element set.

    "Genjikoh no zu"

    See this site. Before it please download Japanese character set.

    You can see all figures and kanjis and names of 52 cases which is 5-th
term of Bell number.

    For example, No.5 represents {1,2}{3,4}{5}.
    You will understand easily the law of figure. At a cross point, it is
not jointed.
    Next line, you see the kanji which means "young violet".
    Last line, the name "waka murasaki"
