 The following example was taken from HOL/ex/PresburgerEx.thy, where it says:
 
   This following theorem proves that all solutions to the
   recurrence relation $x_{i+2} = |x_{i+1}| - x_i$ are periodic with
   period 9.  The example was brought to our attention by John
   Harrison. It does does not require Presburger arithmetic but merely
   quantifier-free linear arithmetic and holds for the rationals as well.
 
   Warning: it takes (in 2006) over 4.2 minutes!
 
 There, it is proved by "arith". (smt (verit)) is able to prove this within a fraction
 of one second. With proof reconstruction, it takes about 13 seconds on a Core2
 processor.
