4*(93!)+1 factors as:

22264972703599697

the sequence is ready to 109:

93(-),94(-),95(+4),96(+3),97(-),98(-),99(+6),100(-),101(-),102(+5),103(-),104(-),105(-),106(-),107(-),108(-)

list of factors is at:
http://stefan.guninski.com/seq/guyres2.txt

the cofactor of the 109th candidate is 174 digits and i don't plan to do
it.
