%N A088141 a(n) = the largest k such that, if k samples are taken from a group of 
               n items, with replacement, a duplication is unlikely (p<1/2).
%C A088141 Related to the birthday paradox. This is essentially the same as A033810.
%e A088141 a(365)=22 because if 22 people are sampled, it is unlikely that two have 
               the same birthday; but if 23 are sampled, it is likely.
%Y A088141 Cf. A033810, A072829.
