Is 8795 especially uninteresting

Me, in a comment on the "185 is special" topic:

<<  I looked a while back (sometime last year?) for the smallest positive 
number not listed among the terms of any sequence in the OEIS, and I think 
it was somewhere in the upper 9000s.  I don't know if it's still in that 
range....  >>

Oops!  I think I was thinking about 9734, but had forgotten about 8795, of 
which I was reminded just now in running across the page at

http://math.crg4.com/uninteresting.html

(which I thought some SEQFANs might find interesting).   :-)

Dear Seqfans, I am not a regular PARI user. The other day
Joerg A. sent this program for A129755:
for(k=1,100,t=(k*(k+1))/2,if(isprime(t+10),print1(k,", ")))
I cannot get it to work.
I don't know if the prgram is wrong or - more likely -
I am doing something wrong. Look:

fry$ gp


Type ? for help, \q to quit.
Type ?12 for how to get moral (and possibly technical) support.


parisize = 4000000, primelimit = 500000
? for(k=1,100,t=(k*(k+1))/2,if(isprime(t+10),print1(k,", ")))

I can't see anything wrong!

What am I doing wrong?

Thanks

Neil
