The decoder needed 47 GBytes of RAM to handle the
very long list.

The symbol error rate was very high at 45.5% which might
be the most errors ever corrected by EbNaut.  With about
50% of the symbols correct just by chance, the signal was
strong enough to bias the noise in favour of a further
4.5% of symbols.  Certainly the highest list rank ever
decoded.

The high BER and high Eb/N0 are a symptom of the high CRC
overhead.
