An alternating sequence achieves discrepancy one for step size one but fails immediately for step size two.
Strict alternation keeps consecutive partial sums tightly controlled. Yet when sampled at step size two, the subsequence becomes constant. This instantly generates steadily growing sums. Larger step sizes produce other patterns of reinforcement. The theorem confirms that no periodic alternation can avoid such destructive multipliers. Infinite alternation cannot suppress discrepancy globally. One multiplier suffices to trigger divergence.

The fragility of alternation is striking. A pattern that appears perfectly balanced collapses under simple scaling. Multiplication rearranges structure in unexpected ways. Infinite repetition amplifies the damage. A single arithmetic lens reveals runaway growth.
This example illustrates how fragile local symmetry becomes under global constraints. Periodic design cannot neutralize multiplicative sampling. The discrepancy theorem formalizes this collapse universally. Infinite alternation offers no shield against arithmetic escalation.
