[seqfan] How to respond to a message?

[Harry J. Smith]

I would like to respond to a message I found at
http://list.seqfan.eu/pipermail/seqfan/2009-January/000494.html but I don't
know how. I will do it here:

 

There is more wrong with the b-file than a(1)=6661 being missing. All terms
starting with 666 like a(6) = 66601 are also missing. I will send Neil a
corrected b-file for n=1,.,20000 (1 6661 . 20000 68466659).

 

I used this PARI program to generate it:

 

digitsIn(x) = 1 + log(x)\log(10)

{

  allocatemem(932245000);

  default(primelimit, 4294965247);

  m=1;

  forprime (p=6660, 68466670,

    d=digitsIn(p);

    for (i=1, d-3,

      t=10^i;

      u=p\t;

      x=u-(u\1000)*1000;

      if (x==666, print(m, " ", p); write("b131645.txt", m, " ", p); m=m+1;
break;);

    )

  )

}

Also, Mmca code may be made shorter (and faster):
 
%t A131645 Select[Prime[Range[300000]],!StringFreeQ[ToString[#],"666"]&]
