Which of the following describes the 'Prime Gap' extgn=pn+1−pn ext{g}_n = p_{n+1} - p_nextgn=pn+1−pn behavior as no∞n o \inftyno∞?
extgn ext{g}_nextgn is bounded by a constant
lim supno∞extgn=∞\limsup_{n o \infty} ext{g}_n = \inftylimsupno∞extgn=∞
lim infno∞extgn=2\liminf_{n o \infty} ext{g}_n = 2liminfno∞extgn=2 (Twin Prime Conjecture)
Both b and c are conjectured/proven
