Hello,
In http://www.primepuzzles.net/puzzles/puzz_041.htm, section B the following
sequence is defined:
Palindrome1 / Sum-of-digits(Palindrome1) = Palindrome2.
First few terms (skipping the trivial 1..9):
Pal1 SOD(Pal1) Pal2
279972 36 7777
2774772 36 77077
5499945 45 122221
25477452 36 707707
27722772 36 770077
254545452 36 7070707
277202772 36 7700077
279999972 63 4444444
Is Pal1 sequence of interest?
If so, should Pal2 and SOD(Pal1) be added as separate sequences?
Best regards,
Lars B
