You could cross check with the file called ECM98, available on
Manfred's homepage. Ecm98 is the finished product of many of the members
of this CCC site (Amir Ban in particular). If you download ECM98 the
ID numbers start at number 1, so for the postions you entered you must first
subtract 938. So your 1075 is ECM98's 137.

I did a quick check on your first five that you listed but only 1080 (142)
and 1188 (250) are present in ECM98. That would indicate that we found errors
there or multiple solutions that were too easy. We also changed some of the
solutions to better ones based on the consensus of the contributors here
on CCC (Bruce, Amir, Bob, Ernst, Don, Christophe, Wren and myself worked
on this. Sorry if I missed someone - it was a nice group project. I even
received numerous emails of how programs did on it and suggestions as to further
refinements).
