Oh, there is a lot more structure than that: those numbers
are exactly

01110000 + a0.00000001 + a1.01010010 + a2.00000100 + a7.10000000
11010000 + a0.10000001 + a1.01010010 + a2.00000100

(in binary, a0,a1,a2,a7 are 0,1, + is exclusive or).

William, can you post those 24 numbers in the order you got them
out of the chip please?
