%N Fold a square sheet of paper alternately vertically to the left and horizontally downwards; after each fold, draw a line along each inward crease; after n folds, the largest region in the resulting graph occupies a(n)/2^n of the whole sheet.
%C A342759 is the main sequence for this entry.
%C The sequence {a(n)/2^n, n >= 0} is bounded and weakly decreasing, hence it has a limit.
