None of the ones I've factored look like ECM misses, but that doesn't prove anything about other numbers. Chris |

Hi Chris,
The only info I've got on how much ecm effort has been done is here. It states "We would be surprised if many factors of less than 25 digits are still to be found." The ecmnet project was working on these numbers, but I don't know how much they did. Cheers. |
