Firstly,another thing I've realized,I never introduced myself to the
group. For what its worth,I work in the Medical Physics Dept.@Guy's
Hospital,London. My interest in prime nos is part-time. Hence,I'm
going to end up saying the obvious or end up treading on old ground.
Hope you have the patience to put up with me.
Anyhows, my latest line of thought: there will always be a prime no
very close to the square of a prime no.

eg.
121(11x11), prime=127
169(13x13),173
289(17x17),293
361(19x19),367
529(23x23),541
841(29x29),853

Does this break down with the larger primes ?

• ... But you must be more specific. How close is very close ? To make this statement even vaguely acceptable, you d have to look at a hell of a lot more primes

But you must be more specific. How close is 'very close'? To make this
statement even vaguely acceptable, you'd have to look at a hell of a lot
more primes than those.
