%N A071792 Decimal expansion of the fourth (of 10) decimal selvage number; the n-th 
               digit of a decimal selvage number, x, is equal to the tenths digit 
               of n*x.
%C A071792 The selvage number, x = sum{k=1..inf} a(k)/10^k, is a normal number, 
               but it is not known whether or not x is irrational. Is this sequence 
               periodic?
%F A071792 a(n) = floor[10*(n*x)] (Mod 10), where x = sum{k=1..inf} a(k)/10^k.
%e A071792 a(5) = 8 since floor(10*(5*x)) = 8, x=.37148269370482593604815926047158260371482693704825...
