Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 3 generators on 28 points:

(2,3)(5,6)(7,10)(8,11)(9,12)(13,14,16,18)(15,17,19,20);(1,2)(3,4)(5,7,9,8)(6,10,12,11)(13,15)(14,17)(16,19)(18,20)(21,22)(23,25)(24,27)(26,28);(1,3,4,2)(6,11)(7,8)(10,12)(17,20)(22,25)(23,28)(26,27)

Polycyclic presentation:
