• Structure of Group

(C3 x C3 x C3 x C3) : (C2 x C2 x C2)

• Generators of Automorphism Group (Permutation Representation for GAP)

r0 := (2,5)(6,9)(7,10)(11,12);

r1 := (1,2)(6,9)(7,10)(11,12);

r2 := (1,3)(2,6)(4,8)(5,9)(7,11)(10,12);

r3 := (1,4)(2,7)(3,8)(5,10)(6,11)(9,12);

• Finitely Presented Group Representation (GAP)

F := FreeGroup(4);

r0 := F.1;; r1 := F.2;; r2 := F.3;; r3 := F.4;;

G := F/[ r0^2, r1^2, r2^2, r3^2, (r2*r3)^2, (r3*r0)^2, (r2*r0)^2, (r1*r0)^3, (r2*r1*r0*r2*r1)^2, (r3*r1*r0*r3*r1)^2, (r3*r1*r0*r3*r2*r1*r2)^2 ];;
