Give list of keys per values, guess the formula to generate the values,

{0,1,2,3} => {4,5,6,7}:

Found:  x +4

{10,11,12,13} => {20,22,24,26}:

Found:  2x

{1,2,3,4} => {4,7,10,13}:

Found:  3x +1

{1,2,3,4} => {0,3,8,15}:

Found:  x² -1

{1,2,3,4} => {19,20,23,28}:

Found:  x² -2x +20

Find x in exponents: Make {1,2,3,4,5} => {0,1,2,4,8} find x² instead of x^3/6 -x² +17x/6 -2.

GNU make is probably required.
GMP (The GNU MP library) is required for big integers.
