COMMENT
|
A subset of this is A050809 = primes of the form floor(e^n). Obverse of A117811 = first prime after e^n. Lim_[n approaches infinity] a(n+1)/a(n) = e. - Jonathan Vos Post (jvospost2(AT)yahoo.com), May 02 2006

EXAMPLE
|
a(20) = floor(e^20) - 54 = 485165195 - 54 = 485165141 as there are no primes p such that 485165141 < p < 485165195.
