My old Macsyma gets (c71) PRIME(8200000000); (d71) 205021987301 (c72) PRIME(9300000000); (d72) 233746743437 SPlouffe>Hello, here is a strange bug, type Prime[8200000000] or Prime[93000000000] in mathematica and your machine will hang forever.... rwg> No, mine is powered by PG&E. and by a bizarre coincidence, the same thing happens with pari-gp with the value prime(8200000000), I could not test 93 000 000 000 because it is out of reach for pari-gp (I think). Does anybody has any idea why the programs are bugging on these particular values ? rwg>NSA back door.
In[156]:= Prime[8200000001] // tim
During evaluation of In[156]:= 0.539572 (secs)
Out[156]= 205021987381 Macsyma took minutes.
Best regards and have a nice day. Simon Plouffe ___________________________
