P16 from M(23760)
I found a P16 from M(23760) (which is a factor of M(3326400)) using Dario Alejandro Alpern's Java factoring program. The remaining composite, C1719, has been added to my ECM Server at wblipp.dynu.com. The server is configured so that 40% of the assignments are for the composite with the least amount of ECM work, so this number will be handed out frequently until it catches up with some of the other numbers.
This is a factor of 2^11880+1. In mersfmt form
M( 23760 )C: 5018022345394081
