My program says 13, 103, 1013, 10039, 100103, 1000193, 10000931 100001903 1000003957 10000003957 100000013957 1000000030957 so I only agree with one of these additional terms. Can anyone check 1000003957 to see if it is indeed a deletable prime? It's smaller than the alternative, so if it's correctly deletable then I think it's the correct next term. I have its deletion path as (1000003957 100003957 10003957 1003957 100957 10957 1097 197 97 7) so I think it's good, and thus have a fair bit of confidence in my remaining terms. More terms coming after someone checks these for me ... --Joshua Zucker
