Presentation

minimal degree	μ(G) = 19
transitive degree	μ_t(G) = 48

A minimal faithful permutation representation — 4 generators on 19 points:

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

Polycyclic presentation:
