Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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