non-incremental/QF_UFNRA/20230328-sqrtmodinv-hoenicke/modInvInitial.smt2

This is a relaxed variant of the benchmark in QF_NIA.
This checks the validity of a line in computing the inverse of
denominator mod 2^256.  The code is:

  assume (denominator mod 2) == 1
  inv1 = (3 * denominator) xor 2
  assert (denominator * inv2) mod 16 = 1
