Rank 4 Tail-triangle diagram with parameters (a,b,c,d) = (4,3,4,4)

Small Group ID = [192,1538], hypertope number 1.

• 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)(3,5)(4,8)(6,11)(7,9)(10,12);

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

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

r3 := (3,7)(5,9);

• Finitely Presented Group Representation (GAP)

F := FreeGroup(4);

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

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