Eric,
You may be interested to know that:
The smallest integer not present in the first 10000 terms = 7968
The largest integer present in the first 10000 terms = 40195
So there is no indication yet that S is not a derangement of N.
Chris

Then what about the graph of Chris' results for the distribution as n
becomes large: does it increase and peak at the prime 7 (the midpoint
between the primes 2 and 17) and is it symmetrical about the prime 7? -- Ed
