[seqfan] Kaku-Stroke-Bus route

[zbi74583.boat at orange.zero.jp]

    Hi,Seqfans

    "Bus route" is the same thing as "Stroke" on non directed graph.
    See the definition on A131709

    To compute number of partition of graph into "Bus route" is rather difficult
even if graph is easy as follows.

    nxn grid  See A135442
    K_n       See A135444
    Could anyone confirm them and compute more term?

    See the definition of "Stroke" on A089243
    It is the abstraction of "Kaku 画" in Kanji writing.
    Kanji   is not only a graph but also a sequence of stroke  on the graph.
