Presentation

minimal degreeμ(G) = 16
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 8 generators on 16 points:

(3,4)(9,10)(11,13)(12,15)(14,16);(1,2)(3,4)(9,11,14,12)(10,15,16,13);(9,10)(11,13)(12,15)(14,16);(9,12,14,11)(10,13,16,15);(9,10)(11,15)(12,13)(14,16);(6,8);(5,6)(7,8);(5,6)(7,8)(9,13)(10,11)(12,16)(14,15)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((3,4)(9,10)(11,13)(12,15)(14,16), (1,2)(3,4)(9,11,14,12)(10,15,16,13), (9,10)(11,13)(12,15)(14,16), (9,12,14,11)(10,13,16,15), (9,10)(11,15)(12,13)(14,16), (6,8), (5,6)(7,8), (5,6)(7,8)(9,13)(10,11)(12,16)(14,15));
