Presentation

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

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

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