n=5 R=120.0: 7405 reachable points, 280965 nodes, max #reflections 148, exact fallbacks 11582, mp calls 0, 4.7s
   types: A0:4193 A1:1606 A2:1606
   alpha in [0,omega], beta in [2pi/n,pi] violated: 0
   Def 2.1 rows as printed (with parity rule) give exactly the exact-formula type: failures 0
   points where a row of the 'wrong' sign also holds: 4; of these with a DIFFERENT type from that row: 2
      these ambiguous points have N in [1] (N=1: the diagonals X_0X_{k+1}, 1<=k<=n-3: expected 2)
   X_0X_(k+1) has type A_k for 0<=k<=n-2: True
   remark 'A_0 <=> beta-alpha=2pi/n' fails for 0 non-diagonal points (for the 2 proper diagonals the remark is not literally true)
