SP: "type Prime[8200000000] or Prime[93000000000]" note the eight zeros after 82, nine zeros after 93 RWG: "My old Macsyma gets (c71) PRIME(8200000000); (d71) 205021987301 (c72) PRIME(9300000000); (d72) 233746743437" note only eight zeros after 93 VM: "I think that macsyma is wrong about 93*10^9: ./primecount -n 93000000000 2560462462787 ./primecount 2560462462786 92999999999" RWG: "? It agrees with (somewhat cajoled) Mathematica: In[159]:= NextPrime@Prime[9299999999] Out[159]= 233746743437" :)
