Presentation

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

A minimal faithful permutation representation — 5 generators on 20 points:

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

Polycyclic presentation:
