make the question comprehensible

| Jan 24, 2012 at 9:06 | comment | added | Gerhard Paseman | In fact, if we use exp(p_r) as a good asymptotic to P_r, then I think the desired quantity approaches r choose r/2 as r grows. But you should get an estimate from a professional. No one pays me for my guesses. Yet. Gerhard "They're Still Worth Something, However" Paseman, 2012.01.24 | |
| Jan 24, 2012 at 8:49 | comment | added | Gerhard Paseman | I could have messed up. I view the problem as specifying a certain antichain in a Boolean lattice of r atoms. I think r choose r/2 is an upper bound, and for large r the lower bound might be something like r choose r/3, but I don't have a proof. What is your take on it?

| Jan 24, 2012 at 8:08 | comment | added | Greg Martin | @Gerhard: I don't immediately see why $r$ choose $r/2$ is either an upper bound or a lower bound for the quantity in question. | |
| Jan 24, 2012 at 3:37 | comment | added | Yemon Choi | The question might be better received if it gave more context, more illustration of what the OP has already tried or learned, and followed suggestions in mathoverflow.net/howtoask | |
| Jan 24, 2012 at 3:09 | comment | added | Wadim Zudilin | I would be more interested in the sum over products of last primes. Jokes aside, very bad way of stating the question... | |
| Jan 24, 2012 at 2:04 | comment | added | Gerhard Paseman | Yes. About r choose (r/2). (It might even be a good estimate.) Gerhard "Ask Me About System Design" Paseman, 2012.01.23 | |
