We have measured elastic compliances for the elongation for several orientationsby the cornposite-bar resonator method over a range of temperature from roomtemperature to - 130'Cinc1uding the upper phase transition (T.= - 79'C) and haveobtained elastic compliances .5.., s.., .5,., s..'r2s.., s,'r2s.., .5..-F-2.5,., .s., and ,s'3,.Elastic anomalies at the upper phase transition and characteristics of the phase transi-lion are phenomenologically discussed based on the irreducible representations T7 atthe point k.=(b.-F-b.)/2 of the space group C:..
