%N Product of all primes up to 3^n.

%C This is the sequence denoted by P_i in van Lint's solution to problem 5412 posed by P. ErdÅ‘s (Amer. Math. Monthly, 74 (1967) p. 874), used to compute the sequence A002038 related to the same problem. The next term, A002037(6), has 301 digits. - _M. F. Hasler_, Jan 02 2013
