對於整數形成的數列,如果不知道名稱,或是不知道相關變化,可以查【整數數列大全】http://www.research.att.com/cgi-bin/access.cgi/as/~njas/sequences/Seis.html 。
如果不是整數形成的數列,有沒有網站,或如何查閱?

Further Hints (OEIS的說明)
If your sequence has decimal fractions in it (1.4, 5.87, 12.083), the OEIS probably can't help you
(though you might try rounding them to the nearest integer, or taking the integer part).

我要找的是 收斂數列,很難避開小數:也嘗試過乘上某數,讓6個數項都是整數,但就如OEIS的說明,找不到!
