"""Permutation-preserving solver for balanced abnormal magic hexagons.

This solver works in the half-turn antisymmetric branch H(-c)=-H(c), H(0)=0.
It never leaves the consecutive shell: the state is always a signed permutation
of 1..m on antipodal cell pairs.  The only objective is the 3(n-1) positive-line
residual vector.

The model is equivalent to three signed triangular arrays A,B,C indexed by
0 <= a < b <= R=n-1.  See the accompanying research note for the formulas.

In case you get such an error:

dyld: Library not loaded: /usr/local/opt/x264/lib/libx264.148.dylib
  Referenced from: /usr/local/Cellar/ffmpeg/3.3.2/bin/ffmpeg
  Reason: image not found
Abort trap: 6

1. Run `brew reinstall x264`
2. Locate the missing library in a new place. For example, mine was at /usr/local/Cellar/x264/r2748/lib/libx264.148.dylib
3. Link the library to the needed place: `link -s /usr/local/Cellar/x264/r2748/lib/libx264.148.dylib /usr/local/opt/x264/lib/libx264.148.dylib`
