Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from its polycyclic presentation:
