[Cryptography] ideas for (long) Nothing up my sleeve numbers

Based on the above I suspect that for this purpose Pi will do.

For an offset into the billions of digits of Pi
I would discard a sane number of digits
based on the digits right of the dp of Pi itself from
math.h i.e.
   lseek(1415926535897^9323846bits) into PI.  ^ marks what seems sane to me.

Thus the only thing needed is a published value
of Pi with a lot of bits sufficient to suffer tossing
many bits away.

1415926535897 does have prime factors.

But not an obvious power of two (byte, int, long, long long.... cache line)
should you wish to eliminate some machine friendly factors.
