Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 8 generators on 20 points:

(10,11);(9,10,12,11);(5,6)(7,8)(10,11)(15,19)(18,20);(6,8)(9,11,12,10)(14,17)(18,20);(3,4);(5,6)(7,8)(13,14)(15,20)(16,17)(18,19);(1,2)(3,4);(13,15)(14,18)(16,19)(17,20)

GAP

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

gap> G := Group((10,11), (9,10,12,11), (5,6)(7,8)(10,11)(15,19)(18,20), (6,8)(9,11,12,10)(14,17)(18,20), (3,4), (5,6)(7,8)(13,14)(15,20)(16,17)(18,19), (1,2)(3,4), (13,15)(14,18)(16,19)(17,20));
