Cancel my previous statement about tour 00o! I was about to put it on =
the website when I found the numerical form, when oriented by the =
Frenicle rule, was the same as 00n. This was correctly stated by GS =
earlier. I was going by the geometrical diagram. But in fact the diagram =
is a 180 degree rotation of the one for 00n. The illusion is due to the =
tour being almost symmetric. Only the positions of four moves are =
altered by the rotation. Sorry about that.
The other new tour, commencing at the corner, gets the name 27t. It is =
remarkably similar to many of the earliest tours found (Mani, Moivre, =
Euler, Collini) in starting in the corner and skirting the board edge =
with a braid.
