[seqfan] Re: Underlined sequences.

[William Keith]

How about the nonunderlined sequence, with a pointer to the two lists of
indices of the underlined and nonunderlined elements?  Or better yet, can a
depiction of the same sequence in the comments take the HTML underline tag?

The OEIS is designed for integer sequences, and its algorithms depend on
that.  Lists that aren't of integers, like words, don't belong.  "O, n, e,
t, w, o, t, h, r, e, e, . . . " is related to integer sequences but can't go
in, while "15, 14, 5, 20, 23, 15, 20, 8, 18, 5, 5, . . .
can.  Coloring, flavoring, or decorating integers makes the original
sequence impossible to submit and I'm okay with that.
