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...pn-1)/(2+3+5+7+11+13...pn)
n-->[oo]
in analogy to phi of Fibonacci numbers?
