Pretty sure that 77^128+1 cofactor is somewhat undersieved. Not sure by how much, but I definitely can't get a matrix.

Well, if it's not undersieved, some help would be appreciated, but... I'm not really sure what else it could be

Yes, it's wildly undersieved (I think I started it out planning to adjust the size later, because I wasn't quite confident with my yield measurements locally); have roughly doubled the number of Q.
