Presentation

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

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

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

GAP

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

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