 OFFSET 0,1 COMMENTS This is the lower limit (limit inferior) as m -> infinity of the sequence of real numbers 1/2, 1/2 ^ 1/3, 1/2 ^ 1/3 ^ 1/5, ..., 1/2 ^ 1/3 ^ 1/5 ^ ... ^ 1/prime(m). The sequence oscillates. A117493 gives the upper limit. LINKS Table of n, a(n) for n=0..104. EXAMPLE 0.60908124348550431887169450547066980...
