n=90 done. Set it off for 300000T to 400000T and it quickly popped up with one just below 304000T so I restarted it on this smaller range.
$ ../dodeca30 90 300000T 304000T
You can also find the k n values in results_dodeca.txt file ( These are 3probable primes )
n=90, kmin=300000T, kmax=304000T, version=3.0, here T=10^12
