Rank 4 Star diagram with parameters (a,b,c) = (4,3,4)

Small Group ID = [192,1538], hypertope number 2.

• Structure of Group

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

• Generators of Automorphism Group (Permutation Representation for GAP)

r0 := (1,2)(3,4)(5,7)(6,8)(9,10)(11,12);

r1 := (3,5)(4,6)(7,9)(8,10);

r2 := (1,3)(2,4)(9,11)(10,12);

r3 := (1,2)(3,4)(9,10)(11,12);

• Finitely Presented Group Representation (GAP)

F := FreeGroup(4);

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

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