Mathematica question: This one is related to superincreasing set of numbers.

Let S={2,5,9,21,45,103,215,450,946};  S={S1,S2,...,S9}

where p=2003, a=1289,  p > Ti

then Ti=a*Si Mod p where T1=a*S1 Mod p = 1289*2 Mod 2003 = 575

Therefore set of T={575,436,1586,1030,1921,569,721,1183,1570} ; 
T={T1,T2,...,T9}

Question: If set of T is given, How can I solve for set of S if a and p 
are unknown? Where S always be a set of superincreasing number.

Your prompt advice is greatly appreciated. Have a Happy Thanksgiving!
