%N A084674 Products of the digits of e excluding 0.
%C A084674 It is interesting that the first 0 occurs in the 14th place of e and the 32nd place in Pi.
%e A084674 a(2) = 14 because, e to two places being 2.7, we have 2 * 7 = 14.
%e A084674 a(3) = 14 because e to three places is 2.71.
%e A084674 a(4) = 112 because e to four places is 2.718 and 2 * 7 * 1 * 8 = 112.
