Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 128

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

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

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

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