Single-formula generation: gray[i] = i lxor (i lsr 1) For n = 4, generates 16 values, each differing from its neighbour by one bit. Output is a permutation of 0..15, so its sum equals the natural-sequence sum 120; +16 entries -> 136. Tests lsl / lxor / lsr together (the iter-127 bitwise ops) plus Array.make / Array.fold_left. 95 baseline programs total.
