Presentation

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

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

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

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