� An algorithm to test the conjecture<br />

It is simple to automate testing the conjecture by collecting the steps above in a function:<br />

TestTripleGeneralizedSumConjecture[n_][x_,y_,z_]:=<br />

Expand[ToScalarProducts[TripleGeneralizedSumA[n][x,y,z]-<br />

TripleGeneralizedSumB[n][x,y,z]]]<br />

As an example of this procedure we run through the first 320 cases. A value of zero will<br />

validate the conjecture for that case.<br />

10.11 Exploring Conjectures<br />

As we have already shown, it is easy to explore conjectures using Mathematica to compute<br />

individual cases. By 'explore' of course, we mean the generation of cases which either disprove<br />

the conjecture or increase our confidence that the conjecture is correct.<br />

A conjecture<br />

As an example we suggest a conjecture for a relationship amongst generalized products of order<br />

1 of the following form, valid for any m, k, and p.<br />
