Presentation

minimal degreeμ(G) = 20
transitive degreeμt(G) = 72

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:
