Proof step 13 from proof fits-law-band (
previous step
)
8 < # int2bits(band(b2i(by1), b2i(by2))) ⊦ ¬ 9 ≤ # int2bits(b2i(by2)), band(b2i(by1), b2i(by2)) = cast(8, band(b2i(by1), b2i(by2)))
Heuristic simplifier applied rule simplifier
And closed the goal!
Rule argument
Additional information
Used simplifier rules: byte-bitlength-01: ⊦ 8 < n → ¬ n ≤ # int2bits(b2i(by));
