Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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

Polycyclic presentation:
