[seqfan] Re: Another surprising omission from OEIS

As I wrote my previous message, sequences about base 2 were in the back of
my mind, and I thought "Maybe I should say something about them," so I say
it now: Their importance in computer applications alone more than justifies
their study. The number-theoretic study of powers of two also occasionally
benefits from considering the binary representation of the applicable

On the other hand, something like "Numbers that are palindromic in base 7
and repdigits in base 12" (a contrived example) I wouldn't care about at
all. But my lack of interest does not mean that such a sequence will or will
not be of interest to anyone besides the submitter. If I see a base uned
sequence that I can fix up, I will, even if I can't see the point of it.
It's not my place to rule on whether such sequences should or should not be
in the OEIS.
