As a followup on that discussion from earlier this month,
i am adding these:


%I A114331
%S A114331 4,6,10,12,14,18,22,26,30,34,38,42,46,51,58,60,62,69,72,74,82,86,94,
%T A114331 99,102,106,108,111,122,129,134,138,146,150,155,158,166,172,178,180,
%U A114331 183,192,194,198,206,218,226,228,232,237,240,249,254,262,267,270
%N A114331 Observe that A052248(n) = greatest prime divisor q (say) of all composite num\
bers between p = prime(n) and next prime. There is only one composite number in this ran\
ge which is divisible by q. Sequence lists these composite numbers.
%C A114331 The uniqueness follows from Bertrand's Postulate. - Franklin T. Adams-Watters\
