Questions where prime numbers play a key-role, such as: questions on the distribution of prime numbers (twin primes, gaps between primes, Hardy–Littlewood conjectures, etc); questions on prime numbers with special properties (Wieferich prime, Wolstenholme prime, etc.). This tag is often used as a specialized tag in combination with the top-level tag nt.number-theory and (if applicable) analytic-number-theory.

For any prime $p$, is there $C$ such that if $x\ge C$, then all but one integer among $x+1, ...

I don't know how far Larry went in pursuing this problem, but this touches on a topic I've spent some time on, ie. Lehmer's method. Let $S_j$ be the maximum $S$ for which the pair {$S, S+j$} is $p$-sm …

Consecutive integers with no large prime factors

Yuta is correct, Størmer's method, or preferably, D.H. Lehmer's 1963 refinement of that method, applies to a finite set of primes. If the set contains $k$ primes, then you have $2^k-1$ Pell equations …
