       Dear Meng,

I am able to find your Murphy_E = 9.43e-10 polynomial with the following:

$ ./cado-nfs.py <rsa120> tasks.polyselect.admax=1e4 
tasks.polyselect.sopteffort=1

However sopteffort=1 will try about 5 times more translations than the default
sopteffort=0. For the record the lucky polynomial is found with skew=101 and
k=-287553. It would be nice to understand why this particular value of k is
good, and to have it included in the list of k-values by default.
