I'd guessed that! ;-)

One example is Woodbine Delight and St Matthias Delight
(6-lead cluster 2515 in Table 10).  These are actually a
two-lead splice, but they do not appear to be listed in
Table 11.

My preliminary search suggests that, after lead splices have
been removed, there are 183 different 2-lead splices between
the 1627 methods listed in Table 2.

When you describe 2-lead splices in book 3, you say,

  This rather esoteric splice is a special case of the
  6-lead splice which requires one of the methods to have
  the 3-4 section { X 56 X }, and the other the more
  conventional { X 12 X } and to be otherwise identical.

Woodbine and St Matthias do not have this property.

Fair enough.  It wasn't intended as criticism -- I think
your books are far and away the best on the subject.

I've only ever used 5-lead splices once or twice, and always
in fairly complicated one-part multi-extent compositions, so
I can see your point.
