n=63 is proving tricky. I've gone to 20000T and nothing. Extending the search to a mighty 500000T (yes, that's 5E17) which should be done by tomorrow afternoon.
n=79 searched to 13000T with nothing, extending to 50000T (5E16).
Update. Got n=63 at a shade under 100000T (1E17).
n=79 has nothing to 20000T, going up to 70000T (7E16) which will take about 13 hours.
