 From the definitions, A051264 should be the same as A171102, not 

However, it appears that n-persistent is being used in a slightly 
different way from what the MathWorld article defines. It seems that it 
is being used to mean that the number is n-persistent as defined but 
not (n+1)-persistent - one could perhaps call this exactly 
n-persistent. Based on that, A051264 is different from the other two 

Certainly the definitions need to be clarified. The other sequences 
referenced in the MathWorld article also appear to be defined in this

Shouldn't  A051264 (1 - persistent numbers)
coincide with A050278 (Pandigital numbers)?

    My friend wrote to the author (of both seqs), in vail,
and asked me.

I think that A051264 == A050278 by definition.
