I get the above too but 54018521 (-) should be on the list between the
last two terms mentioned.
log_phi(33385282)=35.000000000000001864462320812981771451985064099516
log_phi(54018521)=35.999999999999999287838764192951002474040378463974
log_phi(87403803)=37.000000000000000272021386608164000836163367085174
