%N A052110 Decimal expansion of limit c^c^c^c... (with an even number of terms) 
               where c is the constant defined in A037077.
%C A052110 In fact, since the alternating sum in A037077 converges to two sums differing 
               by 1, there are three products produced by c^c^c^... . All three 
               results are shown in the Mathematica program below.
