Presentation

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

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

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

GAP

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

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