Thank you for your verification work. In each case, the 128 bit signature program had the right answer.

Symbolic has produced more than 52,000,000 perft(7) results so far, about 53.94% of the 96,400,068 needed.

There are some challenges at present which may slow the project. Hopefully these will be resolved positively over the next month or two.
