## Main Question or Discussion Point

Consider all primes

2, 3, 5, 7, 11, 13...

and their products such that

2x3=6, 2x3x5=30, 2x3x5x7=210, 2x3x5x7x11=2310, 2x3x5x7x11x13=30030...

Is this latter series used in number theory?

Likewise, can one determine

lim (2+3+5+7+11+13...p

n-->

in analogy to phi of Fibonacci numbers?
