I agree with "no", and that it should have the base keyword.

It might be nice if a comment was added mentioning that this
sequence is 2[n]10 in the "rebase" notation explained in other
entires in the OEIS.

I'd tend to consider these fairly fundamental.  But then it's not clear
what "core" means anyway (although it's at least not as confused as "base"!)

I don't find the random encryption of interesting numbers into 
decimal and their subsequent
explosion into a sequence of digits in any sense "core", but...your 
tastes may differ.

However these should certainly have the "base" keyword added.


BTW, the search "decimal" -keyword:base currently returns 4403 hits, 
with "binary" it's 2637.


Another suggestion: it would be good if all the superseeker 
transforms of all the "core"
sequences could be generated and any missing ones added to the 
OEIS.  That is, the OEIS would
contain the entire "distance-1 superseeker neighborhood" of the core group.

It would furthermore be interesting to know which sequences were the 
transforms of more than
one core sequence, even more so if they are currently missing.
