I can't crack an equatable relevance though. The even sets are symmetrical numeric strings and the odds are variations of of all 9 numbers with the 8 and 7 swapping the 2 and 3. Considering the pattern is infinite and these are the only 4 sets we encounter, I was hoping I could crack some constant between them. You got anything?

Stupid numbers... i love these sequences...

149656941 it's a "palindromo" number

123456789
the second line 1^2 2^2
the third line 1^3 2^3
the fourth line 1^4...

Now if someone asks you what is the last number of a any X^N, you can answer without thinking too much! :P

I knew these sequences and i wonked on them for other reasons for a month. They can be more useful for other things than to answer somebody who asks about that... ;) Believe me!!!

I know!
123456789: Taking the natural numbers series to the (1+4n) exponents (yes, the expoents 1, 5, 9, ...), [n is an non negative integer number], the sequence formed by the unity algarisms of the results is this one.

149656941: The same way, but now the exponents are of the form (2+4n) [yes, 2, 6, 10, ...]

187456329: Now, the exponents (3+4n)

161656161: Yes, you understood: (4+4n)


You just forgot some zeros, but it's ok...
