80% of the way through 10400 curves at B1=6e8 on 149,91 , I found

Code:
Input number is 1012371522143135209861063461009353785010121302172825958296454221759965713253951842644345881909692735642672956070874650916887329062346460647688647191998122286137212717550129078791555167700501 (190 digits)
Using B1=600000000-600000000, B2=9535594068016, polynomial Dickson(30), sigma=3:1955361796
Step 1 took 0ms
Step 2 took 761229ms
********** Factor found in step 2: 2976539548737073923385768026725039346217060034369234629
Found prime factor of 55 digits: 2976539548737073923385768026725039346217060034369234629
Prime cofactor 340116939676705374896498313868317592938750810314047261283507404162853804446948906268514144477866486533969262578500314965032021907805969 has 135 digits
Well, that's a GNFS job we don't need to do.

I am a little annoyed, looking at factordb, that the P55 factor had been submitted anonymously by someone else on 5th March; I kind of thought I had reserved it by http://www.mersenneforum.org/showpos...3&postcount=32

That stinks. You did reserve it back in late Feb. A search of the forum turns up no postings about this particular composite but your own reservation. Poaching or a simple error, it still stinks.
