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! -ENRICO-
