Presentation

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

A minimal faithful permutation representation — 7 generators on 20 points:

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

GAP

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

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