random sequence reversal

["Alain SMEJKAL" <a.smejkal@free.fr>]

Hello all,

Is there a way to reverse a number sequence generated by the random function
?
More precisely my problem is to retrieve the first generated numbers when
many random(k) iterations were done with the same k and the only last random
numbers are known (and maybe useful, the used Pari session is still alive).

ps : Pari version is 2.3.2

Regards,

Alain
