Woll, It always helps if you separate the Mathemaica code for cut and pasting to Mathematica! Here's my effort to get a 24 element (SL[2,3] group) mass Klein-Gordon quantum equation. It appears that the result doesn't have the right angular content for an SU(5) like isomorphic group. If you use p=2 in this it will go much faster to test if it works for your version of Mathematica. Oh, sorry , your code doesn't work at p=2, I just tried it. and got {}. I got it to work for p=3,5. I haven't tried p=7. Roger Bagula Mathematica code: (*SL[2, Prime] : from Carl K.Woll *) p = 3; r = Reduce[Mod[o l - m n, p] == 1 && 0 <= l < p && 0 <= m < p && 0 <= n < p && 0 <= o < p, {l, m, n, o}, Integers]; s0 = {{l, m}, {n, o}} /. {ToRules[r]}; (* Cayley multiplication table*) MatrixForm[Table[Mod[s0[[n]].s0[[m]], p], {n, 1, Length[s]}, {m, 1, Length[s]}]] (* exponential Wave Function definitions space partition functions*) phi[n_] := Exp[x[n]*s0[[n]]] (* Jacobian from Paul Abbott*) jacobian = D[Table[phi[n], {n, 1, Length[ s]}], {Table[x[n], {n, 1, Length[s]}]}]; a = Tr[ Transpose[jacobian] . jacobian, List] // Simplify (* metric as a vector*) guv = a.a (* hyperplane full quantum number wave function of 24 group *) PhiX = Exp[Sum[q[n]*x[n]*s0[[n]], {n, 1, Length[s]}]] (* Klein - Gordon Mass gap*) dd = Sum[D[PhiX, {x[n], 2}], {n, 1, Length[s]}] Aut = FullSimplify[dd/PhiX] FullSimplify[Det[Aut]]
