Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:
