I agree that they are duplicates.  I have submitted a merged version of 

I would recommend that A167348 be retained as a dead sequence instead 
of being deleted; someone may again search for 2,2,3,7,....

Note that these could be considered two valid sequences, one allowing 
only primes and the other allowing non-primes.  Ironically, their 
descriptions would need to be reversed for this to work.

I see that the sequences A091440 and A167348
differ at n=1, because the PARI program in A167348 does not
define primorials smaller than 2, wheras A091440 makes it
very clear what its definition of primorials are. I cannot find
the alternative where p# >= 2 in the OEIS. Does this mean
that A167348 is just an erroneous version of A091440?
