This set of four Dawsonian tours on the 6x6 board complete my search for solutions.
As with the previous batch of four they differ only in the path taken by the 25-36 linkage.
Since my search has been made "by hand" not by computer programming,
it is quite possible I may have missed one or more solutions,
I also recorded a number of "near-misses" where one of the knight moves
is replaced by some other, such as a wazir, rook or zebra move,
bit these don't seem to be of any particular interest.
