Informal Benchmark HW C vs HW D

[John Keith]

If any size greater than 141 causes a crash, there must be a limit of 20000 elements somewhere, since 141 is IP(SQRT(20000)).

Also an 800 x 800 matrix requires 64 times as much memory as a 100 x 100 matrix, not 8 times. I doubt that any hand-held device could invert an 800 x 800 matrix but I'm prepared to be pleasantly surprised.
