Did you mean A002780? The idea that we update the sequence ourselves is the
right way to do it, I feel.
Anyway, now there is unneeded inf in this sequence.
<Start>
"There are no further non-palindromic terms (other than 2201) up to 10^11. -
Matevz Markovic, Apr 04 2011. There are none up to 10^15, by direct search.
- Charles Greathouse, May 16 2011
There are no non-palindromic terms in the range 10^15 to 10^20 with digits
from the set {0,1,2}. - Hans Havermann, May 18 2011."
<End>
I suggest that we compact them into something more readable, like the latest
search limit and who conducted it in the past, like such:
<Start>
"There are no further non-palindromic terms up to 10^15 (Matevz Markovic -
10^11, Charles Greathouse - 10^15, May 16 2011).
There are no further non-palindromic terms in the range from 10^15 to 10^20
with digits from the set {0,1,2} (Hans Havermann, May 18 2011)."
<End>
What do you think?
