Presentation

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

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

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