Exclamation Here's an odd one

I batch factor my aliquot composites overnight, so I don't have anything but the log on this one:
Code:
factoring 55213655784106271888811487247969833626739949447886509091046186980242042559027585931 (83 digits)
. . . . . 
matrix is 44650 x 44762 with weight 1045028 (avg 23.35/col)
matrix includes 64 packed rows
commencing Lanczos iteration
lanczos halted after 707 iterations
recovered 3 nontrivial dependencies
c83 factor: 55213655784106271888811487247969833626739949447886509091046186980242042559027585931
elapsed time 00:25:26
I'll throw it back in the mixer for one more round....
