Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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

Polycyclic presentation:
