Proof step 5 from proof uint2bits-false (previous step)

uint2bits(i) = false ' + false ' + bits, uint2bits(i).rest.first, 0 < i ⊦ 0 = i

User applied rule insert equation

And closed the goal!

Rule argument

pos: left 1 flags: discard

Additional information

Used simplifier rules: ⊦ (boolvar ' + bits).rest = bits;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ (boolvar ' + bits).first ↔ boolvar;
