%N Number of permissible patterns of primes in a fixed interval.
%C pp(w)=w+sumi(sumj((w-i+1)*pb(j,i)) were pb(j,i) is A023189.
%C Similar to A023192. (Here we ignore the empty pattern and start at 0.) These are called "admissible constellations" of primes. - _Don Reble_, Jun 12 2004.
%H Similar work at <a href="http://www.opertech.com/primes/k-tuples.html">Permissible Patterns</a>
%e pp(5)=9 because primes can exist in interval as x.... .x... ..x.. ...x. ....x x.x.. .x.x. ..x.x or x...x
%Y Cf. A008407, A020497, A023189. Equals A023192 - 1.
