** A. High energy string scatterings**

1. We use three different methods to derive infinite linear relations among high energy scattering amplitudes for string states at arbitrary mass levels in the fixed angle regime. All three methods give the consistent result.

2. We derive an infinite number of ratios among string scattering amplitudes of different string states and, FOR THE FIRST TIME, complete the proof of the famous conjectures of Gross in 1988 on high energy symmetry of string theory.

3. We discover an infinite number of recurrence relations among Regge string scattering amplitudes of different string states at arbitrary mass levels.

4. We extract ratios among high-energy string scattering amplitudes in the fixed angle regime from high-energy amplitudes in the Regge regime. The calculation is based on a signless Stirling number identity in combinatorial theory.
