Rank 4 Star diagram with parameters (a,b,c) = (4,4,4)

Small Group ID = [288,889], hypertope number 2.

• Structure of Group

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

• Generators of Automorphism Group (Permutation Representation for GAP)

r0 := (7,9)(8,10);

r1 := (1,2)(3,5)(4,7)(6,8)(9,11)(10,12);

r2 := (2,3)(4,6)(11,12);

r3 := (2,4)(3,6);

• Finitely Presented Group Representation (GAP)

F := FreeGroup(4);

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

G := F/[ r0^2, r3^2, r2^2, r1^2, (r0*r3)^2, (r2*r0)^2, (r2*r3)^2, (r1*r3)^4, (r1*r2*r1*r3)^2, (r1*r2)^4, (r2*r1*r0*r1)^2, (r1*r0)^4, (r1*r0*r1*r3)^3 ];;
