I created the anti-identity matrix by using small program.
casio fx-9860g slim: -29 in 29 seconds
casio fx-cg50: -29 in 6.5-7 seconds

Could you post that 9860 program here, or perhaps in "Not Remotely HP" sub-forum? I might keep an eye out for it, as it took me nearly 12 minutes to enter it by hand. I've done filling lists automatically, but not matrices. Annoyingly, my 9750g+ can't work with a matrix that large. It can create the initial matrix, but there's not enough memory left over to work with it unless I removed the other programs I've got installed.

9750gII: -29 in 20.5 seconds (without any speedups), 4 seconds (sped up to max)
